Here is an Authentic Tiffany Co. Elsa Peretti Black Jade Open Heart Pendant Necklace, on a 16" Chain, and it comes with the little blue box drawstring pouch. I love this off center heart design by Elsa Peretti. Black Jade is an etheric bodyguard and a stone of protection. It's strong elemental energy shields not only the body, but guards against negative forces or entities, energy vampires and people projecting anger and aggression. Associated with the Heart Chakra, Jade is useful to treat stress, anxiety and disorders of blood circulation. The sign of Virgo, it is the stone of love, power and excellence. The pendant measures 13mm wide by 11mm long, and the chain measures 16" long. The chain is Hallmarked "(c) Peretti" on one connector bar, and "Tiffany Co." on one side, and "925" on the other side of the other connector bar, and they both weigh approximately 1.9 Grams. The pendant and chain are in great condition, with minor sign of use. The Tiffany box has some light smudges, and the drawstring pouch is in like new condition, but still ready for gift giving.
