There are chess sets, and then there are chess sets. This one is made in a rare material that has beauty very much on it's side. It's solid (and very heavy) Marble. The lines of the marble are natural and just look great. The set comes in a velvet case and with a heavy solid marble board included.
This kind of black marble is difficult to source but is worth the search. The swirling polished artistry makes a chess set that is simply wonderful. No wonder that ths set has been in so much demand!
