It is formed of unevenly shaped dark brown crystals often with metallic mica reflections. There are some very thin veins in the stone that sometimes look like cracks. They are not cracks at all though, it's just the coloring of the stone.
Overall this granite looks pretty uniform. A lot of people choose this granite when they like marble but don't want to use it in their kitchen.
Antique Brown is also called Marron Cohiba, Brown Antique, Marron Antique, Marron Antico and Auckland Brown.
I especially love Antique Brown with a Honed finish. A Leather or Satin finish is also really beautiful on this stone. The photo below shows the Honed (matte) finish. Also, notice the veins that I was talking about?
Antique Brown is available in 2 cm and 3 cm slabs.
