This stunning marble is from Mark's Geometric series, a piece of history from 2004. These incredible patterned marbles are made using the graal technique, with a thick layer of crystal dipped and laid over the pattern. The result is WONDERFUL! Normally this marble would sell for much more, but it has a very small 1/8" long scratch on it which you can see in the middle of the 2nd pic, so the price has been soundly reduced as a result. Still an incredible marble and it's very hard to see unless you're looking for it. A chance at history for a discount!
