That's a good idea Patty - do a room a week and by the time I get back to the first room full of rocks they'll need cleaning off again! :) I have a few very special ones in an antique glass front Mission oak bookcase. Most of them are little treasures I found while digging around in the "rocks by the pound" section at the quartz mine. Phantom quartz and double-ended crystals are in there along with some small American Indian pots and baskets and carved fetishes purchased in my travels. (I buy the tourist trade fetishes, lovely and made for looks, not for special potency. No cultural appropriation intended.)

The guy at one mine in Mt. Ida, Arkansas, I visited a couple of times had a kids digging area where they could be occupied while parents shopped, so I had time to come up with a couple of fist-sized clumps of muddy rock on the discount uncleaned rock table; they were clearly double ended clusters. He honored the sale, but his eyebrows rose and telegraphed his disappointment at having missed those. I took them home to soak and clean with a toothbrush then soak in Iron Out or one of the other heavy duty stain removers to take the iron mineralization off of them.
