These two stones are entirely natural, both are of high quality, and each piece is authentic and unique. The difference lies in the fact that the CLASSIC material has dotted and continuous veins. Although all pieces are different, they tend to be more uniform. On the other hand, the EXOTIC stone is characterized by having elongated veins; each slab is entirely different, and despite being made of the same material, all its veins are distinct. This material is harder to find, but at first glance, this stone is truly wonderful.
