I’m not sure of the exact name/type of these stones. I believe the black one could possibly be snowflake obsidian. The blue one may be blue aquamarine. The multicolored bracelet has rose and clear quartz it seems, and I’m not sure what others. Selling as is! These are 2 elastic bracelets and the blue beads are just on a string being sold as is. Can be repurposed to make new jewelry, in an arts & crafts project, or added to your natural stone/crystal collection.
