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. A small amount of the GG was marketed as Starburst.
 
This cabochon weighs 8.9 carats and measures 1.5cm in diameter. It is not treated and was backed with black jade by Rob Stapp. It is priced at $100 a carat or $890. GG Apache Blue is rare and the small amount sold as Starburst among the rarest of all turquoise. I have assigned a TG of 93 or GG. I purchased this stone from Rob Stapp who was representing the miners who said this was their claim. Testing by XRF analyses shows that this is Apache Blue.
