SOLD! Well, these are spicy. They were acquired while sitting in a cafe on old Route 66 where Native people often come in and sell their wares. The maker incorporated a piece of the popular turquoise/spiney-oyster mix and surrounded it with some nice inlay work. The backside is a sheet of mother-of-pearl. Pretty sharp looking. Not counting the hanger the length is 1 and 3/8th's inches, and .75-inches across at the widest point. Weight is 4.2-grams, or .145-ounces. The mother-of-pearl on the back prevents any hand stamping for a hallmark. Always complimentary Priority shipping within the U.S.
