Red Variscite

The color of these Variscites is extraordinary, deep red, and especially unusual for the species, placing them among the best known.
Analysis indicate these Variscites are slightly ferroan (which is normal considering that Al and Fe form a series). We think, however, its color is not due to iron because the center of crystals is almost uncolored but the external zone is deeply colored yet both zones have the same chemical composition. Considering all this we think the red color may be due to color centers as is the case of some zoned Fluorites.
As we normally do in these cases we will send the buyer a copy of the analysis.

TH10Y0: Spheroidal aggregates of microcrystals and impregnations of pink Variscite, an unusual color for the species, filling the vugs and fissures on the matrix with Strengite, distinguishable by its bluish color. Both the Variscite and the Strengite have been analyzed and we’ll send a copy of the analysis to the buyer.

Anatase and Rutile epitaxial

One of the main novelties during the Ste. Marie-aux-mines Show 2003 was the new find of huge Anatase crystals groups which are epitaxial with their polymorph Rutile. To our knowledge these new crystals have never been found before in this shape and size. It is not only something very aesthetic and totally different from other forms of Anatase but, considering its size, beauty, perfection and also that the crystals are doubly terminated and floaters, it could be considered to be one of the best finds for this species. Enjoy them!

Doubly terminated Anatase and Rutile epitaxial

AT47Q6: Floater growth of Anatase crystals, most of the doubly terminated and in parallel growths. The Anatase crystals are completely coated by epitaxial Rutile that gives to the piece its characteristics color and luster.
