Sonoran Sunrise "A" Grade Rough from Sonora, Mexico - $64.00/lb
This material is the highest quality Sonoran Sunrise. It has a nice mix of the three colors (greenish, reddish and black) in a tighter pattern. The black area is usually the copper oxide tenorite and on occasion, there is a purplish-gray area that is cuprite. These copper secondaries impregnated a host rock of limestone, which makes Sonoran Sunrise a great lapidary material that is easy to cut and polish.
