Hello all. Need some ideas. So, I found this rough cobble at a place called "Point Pinole" in the San Francisco East Bay. At first I was gong to consider it "leaverite", but I took it home to keep one of my planters from falling over. Most recently, I took a good look at it and noticed it has agatized lines in some spots. So, I would assume it's some sort of jasper-agate mix. My quandary is this: Polishing would almost be out of the question, because of the holes all over the piece. Cutting it is not an option, because of that massive crevice, and you couldn't get a symmetrical, even cut any where. (also, the crevice has pseudo. or wannabe druzy in one spot...so I don't want to alter it)That being said, I really like this piece, but i'm not sure how to prep. it as presentation piece. It look great when it's wet, but extremely dull when dry. any ideas? Thanks!        |

We found a couple pieces about the same shape and size as you show. Set it into plaster of paris and cut it in half longways as it sits the way you are holding it in the next to last pic. May work for you, ours gave us two nice halves to finish the cut face on.

Oh, instead of slicing it to form a front and back (which would alter/break the piece due to the deep crevice)piece, cut it down the middle to form a left and right piece in accordance with the first pic?

If the crevice is too deep to cut it longways, that would certainly work. I was thinking of getting the largest "face" available.
