Thank you for viewing. These are K14WG earrings I purchased at a jewelry store many years ago. I believe the stones are sapphire and cubic zirconia, but I don't have the certificate of authenticity, so they may be different. Please understand. These stud earrings feature beautiful black and white stones, with a simple and elegant design. - Color: Black and white stones - Design: Stud earrings with stones - Material: K14 white gold (stamped) - Earring backs: Dedicated earring backs, K14WG stamped *Price is not negotiable. *Please purchase if you understand these are used items. *No claims or returns accepted. *Please note that items will be shipped in simple packaging.
