NUMBER 8 NEVADA TURQUOISE Number 8 turquoise is one of the most sought-after and valuable turquoise stones in the world. The Number 8 Turquoise Mine in Carlin, Nevada, operated from the 1920s to 1976, producing vibrant blue-green turquoise with distinctive spiderweb matrix patterns. Located in the Lynn Mining District at 7,000 feet, it’s part of the mineral-rich Carlin Trend. Prized by collectors and jewelers, its turquoise is used in cabochons and Native American jewelry. Limited production in recent years has increased its demand and value, making it a sought-after gemstone.
