PLEASE READ FULLY *SIZING INSTRUCTIONS BELOW* This bracelet is made of all genuine faceted 4mm Golden Obsidian and black stainless steel. It's put together with soft, polyester string with a no-show knot. Obsidian is a protection stone and does its job well. The main focus behind Obsidian is for its protective nature. Obsidian obsorbs negative energies, nearly drowning them out. Obsidian is also used to block psychic attacks. Made with care by me. *Sizing: 1st, measure your wrist with string. Bracelets fit best at least 1/4" larger than the wrist. IMPORTANT: Bracelets fit smaller than the length specified. For 10mm bracelets, add 1cm (7/16in). For 8mm bracelets, add 8mm (3/8in) to the size. For 6mm bracelets, add 6mm (3/16in) to the size. Please feel free to ask me about Sizing. I'm here to help! **Don't see your size?
