Set in 18K white gold, this exotic and fashionable black diamond Tahitian south sea cultured pearl ring features a perfectly round, perfectly clean black green pearl set aside a gold and diamond surround. A staple of any woman's wardrobe, a pearl ring is a classic that can accompany her through all the important occasions of her life. Black pearls with the sought-after green overtones are amongst the rarest colors. This pearl is "A Quality", the highest grade of the A, B, C and D nomenclature assigned to grade black diamond Tahitian south sea pearls. The allure of the black pearl is in the way it captures light, refines it and delivers it back in a dark incandescent glow. This ring features an 10mm pearl and .36 carats of G color, SI1 clarity diamonds. Unlike gems that are extracted from the earth and polished, the pearl is the only gem originating from a living organism.
