Happy Birthday to Plymouth!

I’m not sure it’s ever been explained in this blog, but Dearborn Jewelers isn’t actually in Dearborn anymore.  After 53 years, the store moved to Plymouth, Michigan, and that’s where it’s been for the last 14 years.  Those of us who work at the store are very proud of our town.  We support the other businesses as much as we can, we donate to many worthy local causes, and, most recently, we’re contributing to the celebration of Plymouth’s 150th birthday!  

Plymouth was incorporated as a village in 1867 and upgraded to a city in 1932. The “Old Village” was actually the center of town when the Starkweather brothers first settled here.  Over the years, Plymouth has become well known for its special “features”:

  • the only place in Michigan where railroad tracks are laid in all four directions
  • the “Air Rifle Capital of the World” because it’s the home of the Daisy Air Rifle Company
  • its annual events, like the Ice Festival and the Art Festival, earning it the phrase, “There’s always something going on in Downtown Plymouth.”
  • Kellogg Park, once owned by John Kellogg and now the site of about 150 events per year.  To celebrate Plymouth’s 150th birthday, the park’s famous fountain will be re-done, thanks to a generous grant from the Wilcox Foundation.

In honor of this great city, and to help support the Plymouth Historical Museum, Dearborn Jewelers created a one-of-a-kind diamond pendant.  One hundred fifty diamonds, totaling almost 150 points (that’s 1.50 carats), decorate a white gold pendant.  The letters of PLYMOUTH are subtly woven into the piece.  Design elements of the 1860s were incorporated into the pendant. Many of us here at Dearborn Jewelers worked on the design, and we are so proud of our team effort! Someone is going to win this pendant–someone who’s bought a ticket to the Historical Museum event on July 26, 2017.  

Plymouth’s 150 Years Commemorative Pendant, created by Dearborn Jewelers of Plymouth

If you’re interested in supporting the Plymouth Historical Museum and, perhaps, winning a beautiful diamond pendant, buy a $25 ticket from either the museum or from Dearborn Jewelers.  The event begins at 6:00pm and appetizers and beverages will be served.  While the event is sure to be fun, you do not need to be present to win. The winner will also receive a booklet which explains how the pendant was designed and made.  

Good luck to you if you purchase a ticket!  And don’t forget to wish a great big HAPPY BIRTHDAY to Downtown Plymouth!!

 

Pearls 101

At some point you may be in the market for pearls. It’s a complicated topic, but it’s nice to know at least a little bit about what you’re purchasing. Think of this blog as a quick course to help you understand the lingo when you are shopping for pearls. Reading this will also help you understand the wide variation in pricing for pearls.
Lesson 1: All the pearls you see in the store are cultured pearls, which means that they were made with man’s help. Since Mikimoto started growing pearls in the early 1900s, the industry has grown tremendously. Oysters or mussels are tended to by pearl farmers and, when they’re old enough, they get implanted with a piece(s) of tissue(usually from a mussel) or maybe a bead. If all goes well, the mollusk responds to this “irritant” by secreting nacre around it. With time and a lot “babying” on the part of the farmers, these mollusks will produce a pearl. Some mollusks can produce several pearls at one time.
Lesson 2: Different types of mollusks produce different types of pearls. The four main types of pearls you’ll see for sale are Akoya, Tahitian, South Sea, and Freshwater. Of the four, Freshwater pearls are the most economical, partly because many pearls can be harvested from each mussel. Freshwater pearls come in all shapes, sizes, and colors. Akoya pearls are usually white or cream-colored. They’re known for great luster, and they are quite round. Tahitian pearls are gray to black in color, and they’re usually bigger than Akoyas. South Sea pearls can be bigger still, and they are silver or gold in color.

Lesson 3: The shape of a pearl can vary due to many factors, some of them under man’s control. Shape can be described using many different terms. Sure, you’ll hear round, near-round, tear-drop, and button. Those are fairly self-explanatory. But what about BAROQUE? This just means that the pearl isn’t a traditional shape. It’s irregular. Many freshwater pearls fall into this category, because they are normally nucleated with just a small piece of tissue. EDISON pearls refer to freshwater pearls that have been nucleated with round beads rather than tissue. They can be quite big and round because of this. FIREBALL pearls are also bead-nucleated, but they have a “tail” because of the way the bead is placed into the mollusk. MABE, or BLISTER pearls are formed when a half-bead is attached to the inner side of the oyster. When the pearl is removed, a portion of the oyster’s lining is also taken. KESHI pearls are formed when the inserted nucleus is rejected by the oyster, but the nacre has started to gather. The result is a pearl that looks more like a single Kellogg’s cornflake. It is completely made of nacre. MOTHER OF PEARL is not really a pearl, but it’s made of the same stuff. It forms the lining of the mollusk, and can be cut out in thin layers to be used as inlay.

Lesson 4: Just like diamonds have 4 Cs (Cut, color, clarity, and carat weight) that determine their value, pearls have qualities that you should know about. LUSTER is a combo of surface shine and a deeper glow. Really good luster allows you to see your own reflection on the pearl’s surface. If the surface seems cloudy or milky, with more of a matte finish, luster is low. SHAPE, as we talked about in lesson 3, helps determine value. It’s rare to have a perfectly round pearl, but that’s usually the goal. SURFACE is important, too. Blemishes on the surface of the pearl detract from its value. SIZE influences value. Usually bigger is more valuable, because it takes the oyster longer to produce that size. You do have to keep the type of pearl in mind, however. A large Akoya would be a small Tahitian. COLOR is dependent on the type of pearl, too. But it’s important that the pearl have both a pleasing color and fairly uniform color. Finally, if you’re buying a strand of pearls, you need to think about how well they MATCH. Well-matched pearls in a necklace command top prices because it takes so many pearls to find ones that are similar enough to be strung together.

Lesson 5: (optional) If you do plan to buy a strand of pearls, there are some terms you should know. Most strands are made of pearls that are UNIFORM in size and shape. But you can also buy a GRADUATED strand. (No, that doesn’t mean it’s smarter.) It means that the pearls graduate in size, from small near the clasp to large in the center. You can buy strands of different lengths. A PRINCESS length is 18 inches. A MATINEE is 20 – 24 inches. And an OPERA length is 30 – 36 inches long! Or you can buy multiple strands that are worn together as a single necklace. If the strands nest inside each other, you have a BIB. If the strands are twisted together like a braid, you have a TORSADE.

As I said before, buying pearls can seem quite complicated. But they are worth it! And, hopefully, Pearls 101 can help you feel confident.

Mother of Female Jewelry Designers

For centuries jewelry was designed by men. Seems odd, doesn’t it, when most all jewelry is worn by women? But the design field was male dominated for the same reason most fields were–men were seen as the more capable sex and the bread winners of the family. When did it become clear that women could design for women?
Perhaps the first to recognize this talent in a female was Rene’ Boivin, a Parisian goldsmith and engraver in the late 1800s. He married Jeanne Poiret, a woman who became his business partner in his jewelry workshops. Together they created fabulous designs which were in high demand among their elite clientele.

When Rene’ died in 1917, everyone assumed that Jeanne would sell the business but, instead, she and her daughter, Germaine, assumed control. Jeanne, though not trained as a jeweler, knew a lot from working with her husband. She’d think out the designs and have someone else render them. She also had a talent for finding good talent, hiring young Suzanne Belperron in 1921 and, when Suzanne left in 1931, the talented Juliette Moutarde took her place.
Suzanne Belperron opened her own jewelry design firm with Bernard Herz, and later, his son, Jean, in a partnership that lasted over 40 years. Her designs were so distinctive–very fluid and organic. Even while those around her embraced Art Deco, with its straight lines, Suzanne elevated a more modern design. Famous women like the Duchess of Windsor and Mona Williams (pictured below) bought her jewelry. Her work was never signed, though. She always said that her style was her signature.

Sketch and finished piece by Suzanne Belperron

Juliette Moutarde worked with Jeanne and Germaine at House Boivin until they sold the company in 1976. Jeanne had died in 1959, but her daughter, a talented jewelry designer in her own right, kept the business going. Throughout these successful years, custom pieces were never signed by the individual artists. Perhaps it was seen as too bold, too assertive, for a woman to sign her work back in the early 1900s.

Design attributed to Moutarde, made for Claudette Colbert in 1936.

But because of these women, and a few others like Italian Elsa Schiaparelli, female jewelry designers today feel empowered to open their own studios, sign their names to their pieces, and earn their own success in the design world. Thanks to these pioneers, we know names like Paloma Picasso, Elsa Peretti, and Ippolita Rostagno, who have had their own jewelry lines for decades. And because of THEM, contemporary female designers–from Kendra Scott and Irene Neuwirth to Farah Khan Ali and Erica Courtney find success in the always competitive jewelry industry.

Today we don’t think much about gender when choosing a designer. If you like the creation, you respect the designer! But it wasn’t always like that, and I wanted to lift up the courage of Jeanne Bouvin and her team of female designers. They worked and made their way successfully in a male world. Good for them and thank goodness for us. Their combination of talent and determination allowed women who came after to enter the field with confidence. Because of that, I want to nominate Jeanne Poiret Boivin for Mother of Female Jewelry Designers!

My Tourmaline

In 1890 an author named Saxe Holm wrote a charming story entitled, My Tourmaline.  The young heroine possesses a crystal of tourmaline, which she finds in the roots of a large tree.  It brings her good fortune until she loses it.  Bereft until she finally finds it in someone else’s collection, she and her tourmaline are eventually re-united and live “happily ever after.” 

What is it about tourmaline that makes people feel so connected to it?  One reason is because of all the colors it comes in.  There is no other mineral that comes in as many hues.  This rainbow quality translates to a lightness and happiness that appeals to all.  It also suggests tolerance, flexibility and a compassionate understanding.  The Sri Lankans named the gem, “turamali”, meaning a stone of mixed colors.  

A rainbow of gemstones, all of them are tourmaline.

Another quality of tourmaline is its pyroelectricity.  If heated, it actually has magnetic properties.  As a result, the mineral has many industrial uses.  You can find it in hairdryers to calm static hair, in joint wraps to promote blood circulation, and in tuning circuits for conducting TV and radio frequencies.  In the metaphysical world, tourmaline is seen as a strong protector, reflecting negativity away from anyone possessing the stone.  It’s also seen as a grounding stone that promotes a sense of power and self-confidence.  

Finally, tourmaline is a popular gemstone, featured prominently as the birthstone for October and the anniversary stone for the 8th and 38th anniversaries.   It has a hardness of 7 – 7.5 on the Mohs scale, so it’s durable enough to be set in rings.  It’s not as expensive as ruby, emerald, or sapphire, but it can sometimes mimic these colors.  And it’s mined on almost every continent– from the state of Maine to the island of Madagascar.  

You may own a tourmaline and not even know it, because the gem has so many trade names.  If you own a rubellite, an indicolite, a verdelite, a siberite, an achroite, or a paraiba, you actually own a tourmaline. You may also have a bi-colored or parti-colored tourmaline, a watermelon tourmaline, or even tourmalinated quartz!  There are so many different looks to this versatile mineral.  If these pictures are motivating you to own a tourmaline (or a second one), stop in our store.  We’d be happy to introduce you to the ones in our showcase.

A Bracelet Made of Shells

The state of Hawaii is composed of many islands, seven of which are inhabited.  I have to admit that, until I got to visit the state this past January, I would not have been able to name those islands–O’ahu, Maui, Hawaii, Kauai, Lanai, Molokoi, and Ni’ihau.  Most people know about O’ahu.  How many have heard of Ni’ihau?  With a population of about 160, it is a well kept secret and deserving of the name, the Forbidden Island.  

Ni’ihau has been a privately owned island since 1864, when Elizabeth Sinclair bought it from King Kamehameha IV for $10,000 in gold.  Her great-great grandsons, Bruce and David Robinson, own the 70 square mile island now, and they have kept the island isolated and pristine.  The families that live on the island today are descendants of the original families that lived there in the 1800s.  The people have their own dialect of the Hawaiian language.  They live a lot like their forebears.  This is one place where not much has changed. 

The people of Ni’ihau are well known for the beautiful shell leis they create.  Families have unique patterns that they use in their jewelry.  Artists use the tiny shells that wash up on the beach, including the highly sought after Kahelelani shell.  The sale of these leis, bracelets, and earrings is a major source of income for the Ni’ihau people.  Prices are determined by the rarity and quality of the shells as well as the skill of the artisan.  When I was on Maui, I bought a beautiful bracelet that came with its own certificate of authenticity.  I was told that, in the past, there were “copy-cats” who undersold the true artists.  So the certificate is important.  Be wary of shell jewelry that seems poorly made or is extremely inexpensive.

My shell bracelet from Ni’ihau.

If you are planning to go to Hawaii, I would encourage you to learn about the history of Hawaii.  It’s loaded with interesting characters like Captain Cook (not Hook), Queen Emma (wife of King Kamehameha IV),  and even Elizabeth Sinclair (an amazing pioneer from Scotland, who ended up owning an island!)   I loved learning about all the King Kamehamehas (there were five of them) and their wives.  Two royal women,  Queen Kapiolani and Princess Lili’uokalani, can be credited with popularizing shell jewelry.  They traveled to England for Queen Victoria’s Golden Jubilee in 1887, where they wore their long leis and made quite the splash!

The Green Sand Beach

There are four green sand beaches on Earth.  One of them, Papakolea Beach, is at the southern tip of the Big Island of Hawaii.  And I was lucky enough to go there this January, during my 2-week vacation in the Hawaiian Islands.  (Side note:  If you ever get the chance to go to Hawaii, TAKE IT!)   This beach isn’t easy to get to, as it’s about two and a half miles from the dirt parking lot.  Your choices are a “shuttle” which is actually an old van or pick-up truck for $15, or a good 45 minute walk.  Both choices leave you dusty and thirsty, as you make your way towards an amazing oasis.  

The Green Sand Beach

Why is the sand GREEN?  Well, the answer lies under the crust of the Earth, in the upper mantle, where one of the dominant rocks is Peridotite.  The name may remind you of August’s birthstone, Peridot, whose color is a yellowish to brownish green.  Peridotite is brought to the surface on the waves of magma that erupt from the same volcanos that formed the Hawaiian Islands.  It’s made primarily of the mineral, Olivine, which has a much higher melting temperature than most minerals.  So, the magma brings it to the surface, surrounds it with lava rock (basalt), but doesn’t melt it into the mixture.  These peridotite xenoliths eventually reveal themselves as erosion breaks down the basalt host rock.  

What happens next is what happens to every rock, given time and exposure to the elements.  The peridotite breaks into smaller and smaller pieces, until it’s a bunch of tiny olivine grains.  But these little grains are heavier than most sand, so if the conditions are protected enough, they have a tendency to stay.  And if enough of them stay in one place, it makes the beach look green.  Conditions are rarely as perfect as here in this bay, cut by the ocean into the side of a former cinder cone.  

So, how does it feel to play on a beach of green gems?  The truth is, most peridotite is not gem quality, and grains of sand are way too small to be valuable.  But there is something special, at least to this gemologist, about having tiny peridot between your toes.   It was great building a sand castle out of what the Hawaiians call their Hawaiian Diamonds.

The sand is protected by the state, so you’re not allowed to fill a container with it unless you are a native Hawaiian.  But, wouldn’t you know, the driver of my shuttle was a twelfth generation Hawaiian, and he was trying to impress the young, pretty woman sitting next to him.  He gave her a handful of green sand, mixed with larger peridot pebbles, in an empty water bottle.  When she showed them to me, I gasped in delight.  “Oh, my gosh!” I exclaimed.  “They’re beautiful!!”

When she found out I worked with gemstones, she secretly gave me the water bottle, saying, “You’ll appreciate it so much more than I will.”  So, I have my special little stash of green sand which I will keep forever!

Out of this World Jewelry made of Meteorite

Jewelry is made of things from the earth–like metals and minerals.  Or it’s made of animals from the sea–like pearls and coral.  But meteorite is one material used in jewelry that doesn’t come from the earth or the sea.  Meteorite is extraterrestrial material, recovered after it hits Earth.  It’s used a lot in men’s wedding bands, and its use is starting to seep into women’s pendants and bracelets.

Lashbrook's Meteorite Men's Wedding Band

Lashbrook’s Meteorite Men’s Wedding Band

What is meteorite made of?   Well, it depends on which type you’re thinking about.  The three types are stony, iron, and stony-iron.  Only 5% of meteorites are classified as iron, but they are the ones that are used for jewelry.  These meteorites are primarily iron but contain trace elements like nickel, cobalt and gold.  The metal shows a distinctive crystalline pattern when cut, polished, and acid etched.  The pattern is the result of slow-cooling iron and nickel crystals.

One manufacturer of men’s wedding bands, Lashbrook, uses material from the Gibeon meteorite.  The Gibeon material is found near the town of Gibeon in Namibia.  Turns out that all meteorites are named for their location. It’s believed the tons of material that showered Gibeon 30,000 years ago is about 4 billion years old.

Suppose you want a piece of outer space in your ring.  After all, how cool is that?  But you should know a few things first.  Iron meteorites are magnetic so, if your job is working with magnets, you may want to reconsider.  If you have a nickel allergy, you shouldn’t wear meteorite.  Gibeon material is about 9% nickel.  And, even if none of the above holds true for you, you will want to treat your ring with care.  It’s important to never wear it in a pool or hot tub.   Because iron can rust, keep the ring dry as much as possible.  If you do notice rust, rid the meteorite of any moisture by soaking it in 90% rubbing alcohol and then air drying it.  You can clean it gently with a soft toothbrush, and then apply a small amount of gun metal oil, wiping away any excess.  Finally, the etch pattern that makes meteorite so distinctive can wear down and become fainter over time.  It is possible to re-etch the pattern, however.

One thing that surprised me was how many meteorites exist on Earth.  Over 40,000 have been found and cataloged.  Small pieces of meteorite fall to Earth everyday, but most of them are small and impossible to find because they fall into an ocean!  If you want to look for iron meteorite, here are a few tips.  Look in regions that are dry and have a barren expanse, like the Mohave Desert or the Great Plains.  The black to dark brown color of a meteorite’s exterior, due to the fact that it’s on fire when it enters our atmosphere, is easier to see when the land is tan-colored and without vegetation.  Also, the dryness of desert areas helps keep the meteorite from rusting.  Use a metal detector to find iron meteorites.  And check with the land owner before beginning your search.  It’s usually okay to search on public land, but you can’t take any specimens from a National Park.

I have only one tip if you want a meteorite ring.  Come to Dearborn Jewelers!!

What Are You Grateful For?

thanks1

Thanksgiving is my favorite time of year.  I feel that the emphasis on appreciation makes me, at least temporarily, a better person.  When you spend more time thinking about what you’re grateful for, you end up being happier, kinder, and, in general, a more pleasant person.  One of the many things I have to be grateful for is my colleagues here at Dearborn Jewelers.

Not everyone has the encouraging, optimistic work environment that we have here.  We respect and understand each others’ strengths, and we support and help each other when help is needed.  As one of my colleagues said, “We work as a team.  We want to make the other person successful.”  It’s not that we never have disagreements or times of stress.  But we have so much trust in the good intentions of our team members that small disagreements are quickly resolved.

This camaraderie is part of what makes our store so comfortable to our clients.  And because we don’t spend time thinking “grumpy thoughts” about our co-workers, we have more time to think about helping our customers find exactly what they are looking for.  Especially at holiday time, it’s nice to know there’s a place you can go and be treated to a genuine smile and a true desire to help.

As always, we are so thankful for all of you who are friends and clients of Dearborn Jewelers.  We hope you have a wonderful holiday season, filled with family, friends, and good cheer.  But we are also thankful for the family we have here–Nick, Teri, Matt, Emily, Joy, Joan, Jill, and Ellyn.  Happy Thanksgiving!!

Back in Business with Burma

I’ll never forget vacationing in Thailand, trying to decide whether to buy a pair of jadeite earrings.  The beaming salesman chanted to me, “Burmeeeese jade,” with a knowing nod. His smile implied that nothing could be better.

That was about eight years ago, when jade and rubies from Burma (Myanmar) were banned from the United States.  Retailers in the U.S. could not sell them.  Wholesalers could not import them.  Well, that recently changed, and the announcement got me interested in the story of how these gems came to be sanctioned.

It was back in 2003 when George W. Bush signed the trade embargo, prohibiting the import of Burmese goods.  The military ruling group, the “junta”, of the country had imprisoned the people’s leader, Aung San Suu Kyi.  Citizens of the country were having their human rights violated.  The embargo was a response to what was considered an unacceptable way to govern.

But there were loopholes in the 2003 document, and Burmese jade and rubies still found their way into the U.S.  If a “middleman” country got involved, either in the cutting or polishing step, it was still legal to import these gems to the U.S.  That is, until July 2008.

President Bush signed a new document, the Tom Lantos Block Burmese J.A.D.E.(Junta’s Anti-Democratic Efforts) Act, which closed the loopholes and effectively banned the import of ALL precious Burmese gemstones.  Wholesalers and retailers selling ruby and jade needed documentation to certify that the gems had not originated in Burma.

The jewelry industry was negatively impacted by the embargo.  Burma was considered the best source in the world for fine ruby and jade.  Different sources of the gems had to be found, and, over the years, they were.  Today many rubies come from Mozambique. Jadeite sources include Guatemala, Japan, and Kazakhstan.

The trade sanctions had the desired effect.  Myanmar began to make reforms in 2010. Over the next couple of years, democratic elections were held and many political prisoners were released.  In 2011, the U.S.  appointed an ambassador, and, in 2012, President Obama visited the country.  Using a cautious approach, President Obama lifted some of the sanctions in November 2012.  But the ban on rubies and jade remained in place.

Aung San Suu Kyi, who is now the nation’s State Counsellor (sort of like a Prime Minister), expressed patience, saying that “We believe that if we are going along the right path, all sanctions should be lifted in good time.”  And she was right!  On October 7th, 2016, President Obama signed an executive order to lift the remaining trade sanctions against Myanmar.

It will be interesting to see how this executive order influences the jewelry industry in the coming months and years.  It will take some time to establish or re-establish relationships with Burmese stone dealers.  But I believe it won’t be long before we see the deep blood-red Burmese rubies back in our stores.  And my “Burmeeeese” jade earrings (Yes. . . I bought them) may soon be easy to find in the United States.

The Michigan Gemstone

A large polished piece of Greenstone

A large polished piece of Greenstone

In late September I was in Swede’s, the famous light blue jewelry and rock store in the middle of Copper Harbor, Michigan. The feisty woman in charge, 83-year-old Mary Billings, asked me as I walked in–“What is the gemstone of Michigan?”

When I answered, “Isle Royale Greenstone,” she looked at me with new respect.

“You’re only the thirteenth customer this season who has answered that question correctly.  And we’ve had a lot of people who’ve  walked through that door.”  She shook her head, a little disgusted that Michiganders weren’t commonly aware of their state gemstone.

Most people, if they have any idea at all, would probably say Petoskey is the state’s gem.  And it IS the state rock.  But Isle Royale Greenstone, or just Greenstone, has been Michigan’s official gem since 1973.  Found mainly on Isle Royale or the Keweenaw Peninsula, Greenstone has the fancy, scientific name of Chlorastrolite, which is a variety of the mineral Pumpellyite.  It’s often found in and around copper mines, which are abundant in the Keweenaw.  The mineral makes its home in amygdaloidal basalt.  If you’re like me, that phrase holds no meaning.  I had to look it up, so I’m happy to share its meaning.  Basically it’s a pit or cavity in the stone.  So amygdaloidal basalt is cooled and hardened lava with lots of cavities in it that have been filled in with minerals.

Once the Greenstone is removed from its host rock, it can be cut and polished.  But it’s a tricky stone to work with because it’s not really hard–only a 5-6 on the Mohs’ Scale– and it can have its own cavities and hollow spots within it.  Cutters want to expose the best “turtle-back” pattern that they can and eliminate any bad spots.  But removing a top layer of the stone is likely to reveal a different, and not necessarily better pattern. The goal is a clear pattern showing some chatoyancy.  The best stones will demonstrate that change in luster as they are tilted back and forth in the light.

Greenstone is not a particularly expensive gemstone to buy.  Even with the labor involved in finding, mining, and cutting it, there’s just not a huge market for the material.  But it isn’t an easy gem to own.  Since the year 2000, it’s been illegal to take Isle Royale Greenstone off the island. The island is, after all, a national park.  And even Keweenaw Greenstone isn’t easy to get unless you have access to the copper mine areas.  Most jewelry stores, even in Michigan, don’t carry Greenstone.  So plan on spending some time searching for your perfect piece of Michigan’s gemstone.  Whether you spend time looking along the shoreline for a rare small piece of it, or whether you search for jewelry stores that carry the gem, enjoy the journey.
