Hand knotting - The preferred stringing method for a strand of pearls, where each pearl is separated by a small knot. This prevents the pearls from scratching against one another and also from loosing more than one or two pearls in case the strand breaks.

 

Keishi / Keshi Pearls - Keshi pearls are a favorite at Girl with the Pearl. The term Keshi comes from the Japanese word keshinomi, meaning poppy seed. Keshi pearls are unique not only because of their raw and organic shapes, but also because of the way they are formed. Keshi pearls are a sort of by-product of pearl creation, where the oyster rejects the bead nucleus but still forms a pearl without the bead nucleus that is pure nacre. Another way keshi pearls are formed is when implanted tissue fractures and forms separate sacs, and the loose tissue forms keshi pearls. Keshi pearls have amazing sheen and natural luster. 

 

Our best-selling single keshi pearl necklace celebrates our most favorite pearl. 

 

Mabe Pearls - Also known as Blister Pearls, formed on the shell of the mollusk as opposed to between the tissue.
