Scott was a rare lampworker who used soft glass and this gave his vortex marbles a very unique look, set apart by their unusual colors. He also always added dichro to give them that special sparkle. This gem is GORGEOUS and also has a spiral section of dichro on the backside which looks awesome, brilliant all around!! Sadly Scott passed away a while back from cancer, so these marbles are even more special now. Signed 'YD 04' (I believe YD stands for Young Designs).
