All hand-made, hand-stamped and smoothed. Heavy 20 gauge sterling silver, with copper loops brazed to copper back with hard solder.You will need a professional to attest to the type/quality of the turquoise - I was told it is high-quality "Blue Gem". 8 Conchos, each measure 2-3/4" wide X 2" high, each weighs about 1 oz. Take a 3/4 (skinny) belt. At this time, silver artisans did not sign or initial their art. I do not have any receipt or documentation, just her memories telling me of the trip, and a photo of a co-student wearing one bought at the same time/place. I had the items validated by Native artisans at the marketplace event at the Autry Museum. Please write to me if you would like more information.
