Mark used to make clown filigranas (filigrana marbles with 14 different cane) about every 5 years, although I don't think it happened in 2015. This gem is from 2005, which was in my opinion the greatest year ever for MM clowns. The variety of cane Mark used is jaw-dropping, each one flawlessly executed and sooooo beautiful! He created this one on a chocolate base, with the other option being a gray base, and it is HUGE and stunning! Those cane are just so pleasing against that chocolate backdrop. Every serious marble collection needs an MM Clown in it, and I have some great options here. Signed 'Matthews 2005'.
