These are cut from top quality Apache Gold. Apache Gold is the name, not the metal gold. The shiny metallic Chalcopyrite in a black Schist is very hard to photograph. The photos are the best I could do on these stones. The tops are polished.....the backs are sanded smooth.
Apache Gold came from the area of the copper mines in Jerome, Arizona. I've had several very knowledgeable "old timers" in Arizona tell me the actual source is not known. Years ago, it was common practice to bring ore samples from nearby areas to established millsites to be milled and tested. They say a large amount of this material was brought to the mine to be milled and tested. The mines in Jerome shut down soon after and the ore never got milled.
I've been cutting Apache Gold cabs for many years when I could find rough material. When you can find the better quality rough it makes very nice cabs. Many times the black shist is too soft and/or fractured to cut cabs from. There's a similar material from Mexico. These are cut from the true Arizona material.
