There is no purity mark, however it has been tested positive for sterling silver. The inside measurement from tip to tip is approximately 5-3/8" and the opening measurement between the tip is approximately 1-1/2".
Approximate width of the bracelet is 2-1/2. Sturdy 31 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!
