This beautiful three-layer necklace is meant to accentuate not distract from you the total package. With dainty lines and a beautify shimmery druzy stone butterfly pendant. You will definitely love this necklace. Druzy like many gemstones is naturally occurring and happens when water brings minerals to a rock's surface and then the water evaporates. During this process cooling occurs and the minerals are left behind to form crystals on top of the rock.
