Three generations of crystallization have occurred on this limestone matrix. The first to form was a plate of lustrous and translucent, amber-colored crystals of fluorite, to .5 cm across. Next to form were clusters of intergrown, saddle shaped, ivory colored calcite. The third generation resulted in large, lustrous and translucent, ivory colored rhombohedrons of calcite, to 6.5 cm across - including one big crystal perched right at the apex of the specimen; and, remarkably not only is it complete 360 degrees around, but it is pristine! Aside from any locality value, this is therefore an interesting specimen with fascinating paragenesis. Very nice color and sculptural contrast make this one of the better large examples from this famous locality, and quite distinct in its combination from calcite of other locales. In fact, it is very similar to material from old quarries in Shullsberg, Wisconsin - but those of course do not grow on fluorite! Remarkably, there is almost zero damage, and nothing of any bother worth noting, despite the size and 3-dimensionality of this rather large specimen. I am frankly shocked it is in such nice condition. This is from a private collection in Spain, accumulated over decades. It is one of the larger, more 3-dimensional large pieces I have seen come out in such fine condition.
