These are 14k gold-filled cubic zirconia earrings. The zirconia size is approximately 3mm. Although small, they sparkle and add a touch of glamour. Stamped with "1/20 14K". Gold-filled is made by heat-bonding gold to a base metal. The gold layer is much thicker than traditional gold plating, so it won't wear off easily even with long-term use. Total length is approximately 12.2mm. Comes with silicone backings. We offer easy gift wrapping, so they're perfect for presents!
