This blister pearl pendant is handcrafted from .999 fine silver wire and a pretty 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 3/8" x 3" 35mm x 75mm 9mm bail
