It originally cost the person I got the granite and marble from $60,000. The display cases I have are glass and steamed cherry, and cost $20,000 a piece when they were built. I have 4 cases and a few hundred 10x10" marble and granite tiles (Approx 200 marble and 100 granite). Some of the tiles show moderate wear from traffic but are easily "buffed out". I am by no means wanting to trade everything listed for a NIB G36. A few tiles (We can work something out), or a display case and some cash (A tad more than "some"). PM me if interested.
