Coin Pearls

 are a type of Baroque Pearls. The name coin pearls originated from the process of transplanting a coin-shaped nucleus, instead of the traditional round nucleus, into a mollusk.

Appearance
Coin Pearls are shaped like flat buttons with a smooth bottom. They are able to reflect light particularly well because they have a much larger flat surface than other pearls. This provides them with a spectacular luster. They are extremely appreciated in the jewelry making business because they can be used for amazing pieces, such as baroque pearl necklaces or baroque pearl earrings.

Price
When coin pearls were first introduced, they were quite expensive, but as their popularity increased, they became more common and prices went down.
