What is a Coin Pearl?
When you nucleate an oyster or a mollusk with a small round disc (shaped like a coin-right?) you end up with what is known as a coin pearl. Rather than the spherical shape that most people associate with a pearl they are flat and lustrous. They range in size from a dime to a quarter, and everything in between. Just as the size differs, so does the shape-some are skinny, some are fatter, some have lots of dimples and “nipples” and some are perfectly smooth. They can be drilled long ways or top drilled. Jewelry makers favor them for their versatility as they can also be dyed to just about any color you can think of. We love a good coin pearl!
