This blister pearl pendant is handcrafted from .999 fine silver wire and a freeform blister pearl. Blister pearls are real pearls, formed attached to the shell instead of loose inside the shell. As they move, various irridescent colors will appear on their surface. I love my blister pearl pendant. They go great with dressy and/or business attire, they love soft sweaters, and they complement a lot of different outfits. They look great on an omega, chain, or collar, as well as on a satin cord or ribbon. Each of my blister pearl pendants are "one-of-a-kind" and you are selecting the actual one you will be receiving. The chain is not included, but I do have a selection of chains if you need one. approximately 1" x 2 3/8" 24mm x 61mm 6mm bail
