This gemstone anklet is made with Snowflake Obsidian stone beads, onyx accent beads, lead free pewter spacers, & sterling silver lobster claw clasp & chain. The Snowflake Obsidian beads are tube shaped beads, approximately 0.2 inches long & 0.15 inches wide. The size of the anklet can be adjusted based on where you clasp the lobster claw in the chain. There are multiple size ranges available in the variations menu you can select from when you order. Custom sizes are also available upon request. Use a non-stretchy string or flexible measuring tape to measure your anklet where you would wear the anklet to determine the most appropriate size for you. We do not recommend wearing anklets in the water, as it may harm the nylon coated beading wire. Additional anklet lengths available upon request. Please provide a measurement of your anklet size where you would wear the anklet. Use a flexible measuring tape or length of non-stretchy string to measure your ankle.
