The ring is a size 7, but it is adjustable b a size to a size and a half up or probably a half size down at most. The ring detaches so it can be worn as just that for daily use, and then be connected to the hand chain when you want to feel extravagant! This piece is 100% handcrafted (including the chain) from sterling silver and features peridot (in the ring), amethyst, opal and fire opal.
