Mike and James are finally at it again, joining their formidable lampworking skills into a conjoined piece that melds their styles about as seamlessly as humanly possible. Mike's fumed string ball with an opal on top is the core of this marble - all the way to the middle - and James has then triple encased it with layers of fumed dots and lines and millies and his planetary surface features on the backside. Rare and sought after - this heavenly combination of skillage is THE ONE you want!!
