There is no purity mark, however it has been tested positive for sterling silver. The inside measurement from tip to tip is approximately 5-1/4" and the opening measurement between the tip is approximately 1-1/2". Approximate width of the bracelet is 2-1/2(across inside). Approximate size of the stone is 1-1/8" L(North to South), 13mm/little wider than 1/2"W(East to West) (measured from center of the stone). Sturdy 63.7 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!
