A Top 10 "named mine", it was first discovered in the 1920's but has been closed since 1976!!! It is considered one of the premier turquoise's on the market and EVERYTHING on the market comes from the original stockpiles before it closed. A true piece of turquoise history. Most of what they had needed to be stabilized for use in practical ways, so any natural material found is highly collectable and quite rare. These are all natural and directly purchased from one of the original investors of the #8 mine. You don't get any closer to the source than that!!
