Beautiful Blue Forest Slice, Slab with mostly quartz crystals at center. These are far more uncommon than the traditional tree ring varieties. Has pocket of crystals at center then has limb remnants at edges and excellent agate fortification. Polished face measures about 3 x 4. Specimen is just under 1/2 inches thick. The reverse is cut, but not polished. Piece weighs 8 ounces. Very nice.
