Using this pendant necklace is a breeze. Simply open the lobster clasp, put it around your neck, and adjust the single slider bead to your preferred length. As for care, keep it away from harsh chemicals like perfume and cleaning agents, as they can damage the 14k gold plating. When you're not wearing it, store it in a soft jewelry pouch to prevent scratches. Also, remember that because each stone is unique, the colors and patterns may vary a bit from the picture you saw. So, enjoy this beautiful piece and show it off with pride!
