Cabinet, 14.7 x 9.8 x 7.6 cm

White on white but with drama you do not often see...This matrix specimen features a large, tabular calcite crystal with milky overgrowths on the basal faces and glassy and gemmy, colorless, short prismatic faces that you can look right down through to the attachment beneath, presenting an "Oreo" effect in ghostly white! The largest crystal measures 8.5 cm across, quite a significant size for this find from what I saw at Tucson.
