This large and classic "heart twin" of calcite exemplifies the highest qualities in one of these beauties: it is glassy and gemmy, and shockingly colorless. Only a small amount of hematite stains the base of the twin - in this case an aesthetic accent and not distracting as I find most 6of them that are too included and thus murky. A few smaller calcite crystals are perched on the back side of the twin, as well. Ex Pohndorf collection in 1940; then to E. Mitchell Gunnell and still with his label attached. This is another large, classic, and superbly aesthetic calcite twin from the Greenbank collection, which will be remembered for this notable suite.
