Great staple piece! Sterling silver 10mm round disc with hammered polished finish. 23.5ct rose gold plating. Available in polished and worn finishes. The worn finish is designed to naturally wear over time revealing the sterling silver material underneath. Sterling silver post with sterling silver butterfly back. Each piece is individually handcrafted and custom-made per order. Your piece will bear individual characteristics and although equally as beautiful and unique, will vary slightly from the photograph.
