There is no purity mark, however it has been tested positive for sterling silver. The inside measurement from tip to tip is approximately 5-1/8" and the opening measurement between the tip is approximately 1-3/4".
Approximate width of the bracelet 2-5/8. Sturdy 14.8 grams in my scale. This bracelet would be a great addition to any Native American or Southwestern jewelry collection. Also this amazing bracelet is a timeless beauty with lots of good energy! SMOKE AND PET FREE ENVIRONMENT. THANK YOU FOR STOPPING BY!
