Diamantina, Jequitinhonha, Minas Gerais  Brazil (11/2007)

Specimen size: 8.4 × 6.4 × 4.2 cm = 3.3” × 2.5” × 1.7”

Main crystal size: 7.1 × 2 cm = 2.8” × 0.8”

MC14F5: One can see different crystals that have grown in various directions. To me it looks like it is the very complex crystallization that gives the specimen so many faces, which means that any movement creates numerous reflections. It is a very original floater with zones of smoky color and multi-colored reflection from its interior.

TC93Z9: Sharp scalenohedral crystals with very well defined faces and edges, partially coated by small Quartz (amethyst) crystals and implanted on a cavity of the same mineral but with larger crystals. A sample special for the exhibit case, very elegant.
Ametista do Sul, Alto Uruguai region, Rio Grande do Sul  Brazil (2011)

Specimen size: 15.2 × 10.9 × 7 cm = 6.0” × 4.3” × 2.8”

Main crystal size: 5.3 × 3 cm = 2.1” × 1.2”

ET87I1: The crystals are prismatic, and quite thick. Some of them are doubly terminated. Due to their color and luster they have a strong contrast with the matrix of Feldspar. The analysis confirms it is Childrenite. Roscherite, also analyzed, is present as very small crystals covering the Childrenite.

EA11C9: Although the camera don't show it very well, the color is very nice, sort of a golden bronze, and its luster is very special with a lot of reflections. As with the other specimens that we had selected this one is floater, doubly terminated and great!
