Here is a rare marble from Kaj's opal fumer line. I believe this is the first one I've ever seen for sale on the open market, and they are EXTREMELY popular. When you get this one in hand, you will be BLOWN away!! Waves and sheets of super nice fuming surround a killer opal, and then the backside is just AWESOME, with some great unobtanium glass being used. Very, VERY hard marble to let go of!! The pics don't remotely do it justice, SOOOOO much better in hand. You will LOVE this marble.
