This was purchased new as a gift in my family about 20 years ago. Worn only a few times. Stamped “585”, which means 58.5% pure gold (14K). This is an enhancer, which means it can be worn as a pendant or you can open the clip on the back, and snap it onto a strand of pearls (see the pictures - pearls are NOT included, chain is not included. Bundle with chains or pearls in my closet (shown for perspective only). Stone is a genuine, lab grown pink sapphire. The stone is large, probably 3-4 carats. Smoke free, pet friendly home. Thank you!
