This is a very exotic beautiful material. Slabs are made using hand selected semi-precious materials (such as petrified wood, amethyst, different coloured agates, rose quartz and smoky grey quartz, lapis lazuli, calcite orange etc). Each semi-precious stone is hand cut and pieced together, bound with an epoxy resin to create the slab. The result is a luxurious esthetically artistic one of a kind slab. This material requires a longer production time than other materials, but is well worth the wait.
