Stun in sapphire with the 14K. Solid Gold Necklace with Diamonds and Sapphire. This necklace is made up of an 18-inch double link rope chain decorated with a pendant set with gemstones. A teardrop-cut sapphire hangs from a long, wavy vertical bar studded with diamonds. The deep blue of sapphire contrasts with the glittering diamonds. ***The sapphire that decorates this necklace is natural, and it has not been lab enhanced. It may contain inclusions that are visible to the naked eye. The slight variation in the appearance of the precious gemstone can make it a uniquely beautiful addition to this necklace.
