1. A processed slab formed from a plurality of particulate mineral mixes, comprising:
a slab width that is at least 2 feet;
a slab length that extends perpendicular to the slab width and that is at least 6 feet, the slab length and the slab width defining a top major surface;
a slab thickness that extends perpendicular to the slab width and the slab length, the slab length greater than the slab width, the slab width greater than the slab thickness; and
a first pattern defined by a first particulate mix, the first pattern exposed along the top major surface of the slab, and the first particulate mix comprising first metallic particles having a first mesh size;
a second pattern defined by a second particulate mix;
wherein the first pattern defines at least one vein having a first measured gloss at 60 degrees of 75 or greater; and
wherein the second pattern defines at least one region having a second measured gloss at 60 degrees that is different than the first measured gloss.
