Apache Blue is the marketing name for the old Turkey Track claim in Esmeralda Co. NV. It has become a sought-out turquoise especially for the higher-grade dark web.
 
This cabochon weighs 6.9 carats and measures 2cm X 1.50cm. It is not treated and backed. It is priced at $70 a carat or $476. Apache Blue is rare and hard to find in the market. I have assigned a TG of 85 or VHG. I purchased this stone from Ernie Montoya at Sunwest Silver.
