If you're looking for a masterpiece from Mike, then look no further, because this huge stunner is IT!! Three separate classic opal styles from Mike are seamlessly combined into one marble, and the result is INCREDIBLE!! You've got the classic opal vortex with blue-green fuming, then the original Gongsta special: fumed chaos stringer with tear-drop opal, and finally an AWESOME square tab opal hovering over one of his concentric circles (which everybody copies now). You really need to have your explorer's license to be able to truly appreciate this marble, because there is so much to see and study as you twist it around. Love it, VERY hard marble to let go of!! It is incredibly unique compared to anything else I've seen from Mike, not a typical color combo for him. This marble is signed 'M Gong 9.2012'.
