Edison Pearls

Edison pearls are freshwater pearls using techniques also used in cultivating Tahitian, Akoya, and South Sea pearls. 

To understand some of the differences here is some information on how salt water and freshwater pearls are cultivated.

Tahitian Pearls
Tahitian pearls are cultivated in the black lip oyster in the warm salt waters of French Polynesia. A round bead nucleus is inserted into the oyster and is a template for the pearl to layer it's beautiful nacre over the bead and hopefully create a round pearl. Often a baroque, oval, teardrop, or off round shape forms giving a variety of pearl styles! A single pearl is formed in an oyster at a time.

Freshwater Pearls
Traditional freshwater pearls are cultivated in a large freshwater mussel. It is tissue nucleated meaning a small piece of mantle tissue is inserted from a donor mollusk resulting in a pearl that is solid nacre. Depending on the size of the pearls to be cultivated and the size of the mussel, each shell can produce an average of 24-32 pearls at one time! 

This brings us to the Edison pearl.
Edison pearls take the bead nucleated methods of Tahitian pearls and South Sea pearls and combines it with the freshwater mollusk. A single bead nucleated mussel creates one Edison pearl at time. This method can produce rounder, larger, and more lustrous pearls than traditional freshwater pearls.This also results in a more expensive pearl since they are cultivated one at a time, instead of dozens at a time like traditional freshwater pearls.
