Pieces of genuine sea glass are bezel set in fine and tarnish resistant Argentium ® sterling silver and accented with a rose cut citrine cabochon and a sparkly blue spinel cubic zirconia. 22 karat gold has been fused on areas of the silver for added interest. The back of the pendant bears my maker's mark "CC" and the 925 sterling hallmark. A 18" silver plated chain is included.
