The No. 8 turquoise mine in Carlin, Nevada was first mined in 1929 until its depletion. In its prime, No. 8 produced some of the largest nuggets of turquoise found. A spider web matrix of colors ranging from golden brown to black set off the unique bright powder blue background of the stone. High grade No. 8 is deep blue in color and is very rare. No. 8 turquoise has been a very valuable acquisition, rumors of new stashes of great quantity threaten the value from a collector’s standpoint, if they prove to be true, of course the high-grade will always be very valuable.
