Featuring 18k white gold bezel set diamond and pink sapphire,"by the yard", necklace pendant. Diamond weighting 0.08 carats, pink sapphire weighting 0.65 carats. Cable chain necklace 16" long with spring lock: a lock that fastens with a spring bolt. Pink sapphire is set in a twisted rope style bezel setting. Bezel settings use a type of elevated collar which wraps the rim of the gemstone in a complete metal edging. This type of setting is the most secure fastener for the stones. The bezel setting also protects the gemstone better than other types of settings, such as the prong setting. Pink sapphires are available in many shades, ranging from light pink to hot pink and purplish pink. Pink is actually one of the rarest colors in sapphire. Pink sapphires over 1 carat are rare, and a pink sapphire over 4 carats counts as extremely rare.
