Product title: Alluring Beauty - Large Cocktail Ring with Black Mother-of-Pearl & Pavé
Product description: From times immemorial the oyster has been lining its shell with nacre for creature comfort, and man has been seeking it for its alluring beauty! This black Mother-of-Pearl from a Tahitian oyster shell is somewhat of a rectangle with a twist, measuring approx. 21x16mm. Mostly dark grey with shimmery overtones of green and pink, each piece has it own individuality and will steal your heart. At its outer edges the Mother-of-Pearl is embellished by a graduated line pav with White Diamond CZs. The high polish wide band measuring approx. 18mm at the shoulders tapers for comfort down to 10mm at the back. Heavily layered in a high polish Rhodium electroplate over Brass, for the look of White Gold. (Rhodium is one of the metals belonging to the Platinum group). Our stones are expertly hand cut and hand set, and carefully selected for color uniformity. The superb workmanship truly gives our pieces the actual look of Fine Jewelry. *** Natural Gemstones: each one (even in its own category) is unique and may look different from the picture. *** CZs: There may be a slight difference of shade between items from different shipments. Consider to order one size up, since this wide band ring runs half to one size smaller.
