The bezel is made of 925 sterling silver. The piece is handcrafted, so no two will be the same. Take pride in knowing that your necklace is one of a kind. NOTE: Each piece is in its natural state. It’s not coated with anything to prevent tarnish. Oils, lotions, moisture, etc. will accelerate the tarnish, so its recommended that you use a jewelry cloth for cleaning after wearing your jewelry.
