I have a bunch of holey rock. Selling for $1/# regular pieces and showpieces/center pieces make offer. Rocks are bleaching now. I'll give you a deal if you want all of it. Some Rock is a bit more granular, I'm not a pro on the id. Check out the pics and see can for reference. I bet the first Rock is 75-100# at least. Text 614-678-9620 or pm
