Vintage Dyed Polished Mother of Pearl Chunky Shell Stretch Bracelet While researching what the materials were on this bracelet I received a lot of funny comments- smoked oysters, kidney stones, sardines, etc. However, these are definitely NOT any of those! This is Mother of pearl shell that has been polished and dyed. These are VINTAGE items. Scratches, flaws, rubs, etc are to be expected. Anything more than that will be noted in the description. Please use the pics for best description of condition and ask all questions before purchase. All of my items are sold as-is.
