This is a K10YG necklace using black chalcedony from Jouete. Black chalcedony emits a chic sparkle. Its deep color will instantly elevate your styling and give you a sophisticated, modern vibe just by wearing it. The random cut on the stone adds a touch of adult playfulness. This item is packed with carefully crafted details designed to make the stone stand out. Its subtle size makes it easy to wear daily and a versatile piece that transcends age and season. I am selling this because I have purchased additional gemstone necklaces. I hope someone can make good use of it! (^^) *This is a used item.
