Two loops at the top of one side make this heart hang on an angle from a delicate silver chain. I'm pretty sure the stones are synthetic white amethyst. Excellent condition for gifting. I cannot be responsible for unexpected postal delays, but I will ship this piece within 24 hours of your order, if you're trying to get it before Valentine's Day. Approximate measurements: Chain length: 18.5" Heart pendant width: 2" Heart length: 1"
