The other day a customer came in to get her ring sized. She was amazed and somewhat alarmed to learn that our bench jewelers would be cutting her ring with a saw blade in order to size it. Her beautiful ring–a piece of art–subjected to the saw! But jewelry is more than art and more than an expression of sentiment. It’s also a piece of engineering. It’s built with shanks and prongs, bails and bezels, and many other findings. It’s adjusted or repaired with the use of tools like saws, hammers, and torches. Using rings as our example, let’s explore the Anatomy of a piece of jewelry.
MOUNTING: This is the general name for the metal that holds the stone(s) in place and encircles your finger to keep the ring on your finger.
SHANK: This refers to just the curved part of the ring that goes around your finger. Shanks can have profiles(or cross-sections) that can be quite flat to very round. The width of the shank can also vary. And the shape of the shank, while usually circular, could be oval or even rectangular. A EURO-SHANK is curved on the sides but has a squared off bottom. There are adjustable shanks, too, which operate with hinges, allowing more room for a ring to slide over the knuckle.
SETTING: Sometimes a synonym for mounting, a setting probably refers more to how the stone(s) are held in place. Setting techniques include prong or shared prong set, bead set, tension set, channel set, bar set, flush set, bezel set, pave set, and invisible set.
PRONG: Tiny metal wires that suspend the stone, holding it in little “claws” (HEAD), so that light can enter the diamond from all sides.
BEZEL: A frame of precious metal that surrounds the stone, bezels can be thin like a wire or wide so that the side of stone is unseen.
FINISH: Whether the metal is shiny or more dull depends on the finish. You can have a polished finish, which is shiny or a matte finish, which is smooth but less shiny. Other finishes like satin, hammered, engraved or stone can give texture to the surface of the ring.
MILLGRAIN: This is a common embellishment on the shank of a ring. It’s a border of tiny beads that acts as a boundary or edging.
I could go on–there seems to be about ten- thousand terms that bench jewelers use. I learn a new one almost every day. Instead, let’s re-cap with a picture and save Anatomy 102 for another day. The important thing to glean from today is that jewelry is a designed and constructed piece of art. It’s engineered to be art that you can wear.
