Ashley,
Ashley,
You are right. I was confusing keishi with Biwa. Sorry. So, keishis are a by product of cultured pearl production, and are not a cultured product themselves. They are solid nacre. Now, bear with me...keishis are similar to baroque in their unique and unusual shapes, but keishis are solid nacre, whether they are freshwater or saltwater, and cultured baroques are bead nucleated.
Thanks so much for your help,
Judi
