more replies please! more replies please! Caitlyn thank you so much for your reply. I would love some more replies perhaps from vendors/suppliers. There are no more pearls from Lake Biwa. Is it acceptable to call a pearl that is not from the original Biwa Lake "a Biwa". There are lots of...

Thank you Caitlin! I guess I'm asking is it ethical to call a pearl that did not come from Lake Biwa a "Biwa Pearl". The term Ceylon for sapphires is only supposed to be for sapphires that came from that region. However many in the industry deceptively call sapphires of "ceylon" color "ceylon...
