This vortex is deep, dark and fascinating!! The gold and silver snakeskin fuming is wonderful, and it's offset by a textured cobalt pattern in between the snakeskin stripes. The result is intensely beautiful. The backside has Kevin's wonderful raked flower pattern using some of his brilliant hand-mixed sparkle and violet colors, and then some of his awesome chevron milli around the equator. There is a small as-made rough spot on the top of the lens which you can only see when you study the marble under bright lighting. Signed with backwards sig chip 'Kevin O'Grady 2005'.
