The base, made of natural Brazilian green onyx, consists of predominantly green hues with gold and white notes, and sometimes a splash of scarlet. Much like a fingerprint, this blend and swirl of colors is one-of-a-kind and totally unique to the onyx slate. As for the derrick machine, the emerald matte finish is achieved with a light bead blast of bare aluminum prior to anodizing.
