These Oyster Secrete Blister Pearl Shell Focal Pendants measure between 43mm - 45mm (approx. 1.75") with a 4mm - 5mm diameter hole in the top center. Easy to attach to cord or could be wire wrapped. Pearls found attached to the inner surface of the shell are known as "Blister Pearls". This happens when an object of an irritant nature lodges between the mantle and the shell. Note: Photos above shows 12 Pendants but not the exact 12 Pendants you will receive. Photo is a good presentation of the mix you will receive. Photo shows possible variations. Some of these are somewhat convex, some are somewhat concave. Some are Peachy-Pink and some are nearly white or a mix of white and tan. Some are quite thick and some are thin. Some have a TON of blister pearls in them and some have almost none. Some will have spots where a previously attached pearl has fallen off. All are beautiful and unique, no two are identical, just as nature planned it. At the price we have these at we can't really allow for selection, but if you are really bothered by one variation or another we can help you. Need only one? Check out our other listing for these.
