A shockingly good, golden-colored, lustrous, twinned crystal of calcite perched on just the right amount of matrix: Back in the late 90's, we saw hundreds of these, maybe thousands. I certainly paid close attention, as a calcite collector, and bought many of them. Even so, THIS ONE stands just that extra bit above the crowd and is, for its size, one of the very best of the now-long-gone find out there. I would keep it if I didn't have one just a bit bigger and gemmier (though no matrix) for which I paid far more for, and even so I am honestly tempted here....it is truly that extra 10-20% fine compared to others.
