Calcite- gemmy, twinned
Elmwood Mine, Carthage
5.4 x 5 x 2.3 CM (cabinet)
Ultra clear, a pair of transparent crystals of twinned Scalenohedral Calcite from the great Elmwood mine. The faces are glassy and the termination tips show a slight hint of a cognac color otherwise these are perfectly colorless. The twinning is both a rotational and interpenetrated type, which is very easy to see in person. Just a hint of matrix is present, mostly on the backside of one crystal. The condition is fine and the terminations are uncleaved, A contact on the back, lower edge is noted but no damage. Now that the Elmwood is closed probably forever, good, clean Calcites of the quality are becoming quite uncommon and prized.

A clear, colorless Beryl crystal with double termination (crude but complete) and very glassy faces. Fine transparency and interesting internal structures are easily visible. It is surprising how very uncommon colorless Beryl (Goshenite) is. This specimen is ex Les Hitchings collection, obtained in 1968 by him. A high percentage of this is facet grade gem, the backside is contacted and included by Clevelandite but overall the prism is complete and choice.
Simple and attractive, the less common tabular form (flat hexagons) of gem clear Beryl nicely perched on matrix. In most light the Beryl looks white or colorless, but a tiny hint of blue can be seen in some conditions. In my eye it is a colorless Goshenite variety but some may see it as a pale Aquamarine. Either way this presents this special discoidal habit very well. From the modern classic area of Mt Xuebaoding in 2003, this form has not been found for some time. A choice modern Chinese classic and an uncommon crystal habit.
Bright gem clear white Beryl crystals are studded on a 3 dimensional array of shiny black Schorl crystals. In excellent condition, this is a fine Erongo specimen and far better in person. 2012 vintage, this material has not been seen since.
