Vintage Malachite Gemstone Native Sterling Silver Bypass Cuff Bangle Bracelet

Beautiful vintage Malachite gemstone Native American bypass bracelet with a 3/16" wide double half round sterling silver wire bracelet cuff is smoothed down to a single and swooped around the 2 bezel set 9mm malachite gemstone cabochons on either side.  Measures 6.75 inches from end to end but is adjustable and bypass type so can be bypassed smaller than 6.75” and also opened and worn with a larger gap, comfortably up to 8.5” in my opinion.  No hallmarks found but tested 925 sterling.
