Double row of pearls, bought for breaking up for embroidery, glad I checked the clasp was platinum set with small diamonds not sure if they were natural or cultured but it didn't matter . Lost in a burglary a few years later but they were the something borrowed for a few friends weddings before that. Also a small silver bow brooch set with diamonds bought on a charity stall at a car boot sale. I knew it was silver when I bought it, only when I cleaned it I thought it was worth getting it checked. I wear it sometimes but it's a bit too dainty.
