thank you so very much! the individual ones were from a necklace my mother gave me a long time ago that broke while i was wearing it and resulted in the loss of many identical ones. I am told they are natural and not cultured, given to her by her great grandmother. It was a very sad day when they fell from my neck. the color treated pearls are actually green, i adore them immensely, is it true then, that peacock pearls are color treated pearls? thank you again for your response!
