Aquamarine is routinely heat-treated in the trade to remove a green cast, and most blue aquamarine sold today has been heated — heating is permanent and is accepted practice, not a coating. The obsidian is volcanic glass and is not treated at all. If you need fully untreated aquamarine, email us before ordering and we will tell you what is in stock.\u003c\/p\u003e\n\u003ch3\u003eWill an 8 mm bracelet fit my wrist?\u003c\/h3\u003e\n\u003cp\u003eEach bracelet measures about 17–18 cm (6.7–7.1 in) unstretched on 8 mm beads, which suits wrists from roughly 14.5 to 19 cm. There is no clasp to adjust — the elastic core lets it roll on. If your wrist measures outside that range, message us before ordering.\u003c\/p\u003e\n\u003ch3\u003eIs the silver solid or plated?\u003c\/h3\u003e\n\u003cp\u003eSolid 925 sterling silver spacers.
