This necklace is with a natural larvikite stone that measure 48x30x6mm. I have embellished the top of the stone with a silver wire wrap. This necklace has tons of sparkle and varying colors of whites, grays, and blacks. The chain is approx. 23" long but I can shorten or lengthen it to any length. Just send me a convo with the length that you desire. This necklace looks great with the midnight sparkle earrings that I have listed. Thanks for looking!
