This master marble is from Mark's Geometric series, each one of these a sweet piece of marble history! These incredible patterned marbles are made using the graal technique, with black glass layered over white and then the pattern meticulously laid on the marble and blasted away, then completed with a thick layer of crystal dipped and laid over the pattern which makes the whole thing absolutely pop in hand. What a genius design this here is, huh?! Breaking up that wave in the middle like that is just so freaking cool, and it's so clean and tight when you see it in hand. I'm continuously amazed at the mind of Mark Matthews! Signed 'Matthews 2005'.
