Cacoxenite....connects us all on this earth and promotes kindness. Maybe I will send a few stones to a few folks I know who could use a little more connection and a little less hatred.... This bracelet measures near 8.25" but due to stone size fits closer to 7.5" or so. Let it roll on your wrist and remind you we all can get along.... Clasp and crimps are sterling silver. Please let me know if you want to discuss a different length.
