This gem is mind bogglingly cool in hand, and wildly hard to let go of! In fact, I wasn't at first, ha, but have forced myself to let someone else enjoy it. The silver fuming over top of the killer dot stacking is PEREFECT in this one. It's just so ethereal, the type of marble that intrigues the mind and creates that awesome sense of wonder when held in hand! Signed 'Altier 23'.
