Vien pieces with cabs

Here are some vein pieces and the cabs that were cut from this material.The different veins and zones can produce different looks and colors. But these cabs were cut from this zone.This zone the black material ocuurs pure black with a lighter matrix. In this zone also blueish green will mix in the black also. This area seems to occur in very small spheres and nodules to form the vein.Makes a great patterned stone when cut.!!!!!
