14k tanzanite necklace! White gold snake chain and the pendant is yellow gold. The pendant does NOT come off. I think it was custom made this way. It weighs a total of 5.4 grams. The chain is 16 inches total length (shorter than standard). Tanzanite measures about 7.4mm ×5mm (approximately 1 carat). Fantastic quality! Beautiful!
