This product is an 18K gold over .925 sterling silver necklace and earrings set featuring a rectangular-shaped ametrine stone in a purple color. The handmade pieces are crafted with natural ametrine stones that are not enhanced and set in sterling silver with a metal purity of 925. The set is from the brand Technibond, making it a unique and elegant addition to any jewelry collection. I am not sure if these were ever worn, so I am listing them as used. But they come with original boxes. Please see pics.
