This sea anemone vortex is a huge one, with SO much going on down in there! The price might surprise you, being so low for a large cool vortex like this. I had handled and looked at this marble at least 10 times and never noticed it, but when I took pictures of it last night, I saw a tiny pin prick ding on it. It's not something you'd probably ever notice if somebody didn't point it out, but it's there. This would be a $600 vortex otherwise, really awesome for the price. I got this from Kevin back in February, 2011, but it is a 2005 vortex he still had. He rarely, if ever, makes this kind of vortex any longer. A great chance to get a sweet large marble.
