The Number 8 turquoise mine in Carlin, Nevada was first mined in 1929. In its prime, Number 8 produced some of the largest nuggets of turquoise ever found. A spider web matrix of colors ranging from golden brown to black set off the unique bright powder blue background.

Of the ten claims in a 20-acre area, the Number 8 claimed by the Blue Star Company in Lander County is considered the finest example of the gold-webbed turquoise. The mine was depleted in 1961. Approximately 5,000 pounds were mined between 1929-1933. In 1950 a nodule weighing 150 pounds was found. It is now at the Covered Wagon in Old Town Albuquerque, New Mexico. The host rock is naturally altered quartz monzonite shale and thinly beaded black chert.
