This abalone pendant is handcrafted from .999 fine silver wire and a piece of blue abalone shell. This abalone is found off the coast of Baja California, Mexico. You will notice different colors in the abalone, depending on the color you are wearing and the light that is hitting it. It looks great on a chain, neck wire, rubber cord, or leather cord. Depending on the angle and the light, this one can have dark purples, olive greens, bright greens, and pinkish purples, all accented nicely with some blacks. Each of my abalone 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 7/8" x 2" 24mm x 53mm 9mm bail
