A pair of bracelets, one black and one pink, with matching plated spacer beads so they read as a set rather than two unrelated strands. Obsidian is volcanic glass and rose quartz is a coloured quartz; both are natural, and neither is dyed.
Beads are 8 mm on elastic cord. The inner circumference is about 17 cm unstretched, which fits most wrists, but measure rather than assume — an elastic bracelet should need a gentle stretch to go on. Because this is sold as a pair, the beads on the two strands will not match each other exactly.
