Carrollite

Between 2001 and 2003 Congo has given us fabulous Carrollites, which were much better than the older ones. We got hold of many nice specimens that sold well on our web pages. We still run into them when buying from our normal sources and we still see some good specimens which we can offer on our website. Thus we can continue to offer this excellent mineralogical species.

Carrollite
Carrollite.
 

EP56Y6: Group of sharp crystals with very well defined faces and edges showing the forms of the dodecahedron, the cube and a finely striated tetrahexaedron. They have thin Chalcopyrite coatings, are very bright and their morphology is most unusual for Carrollite from Kambove.

Specimen size: 2.5 × 2 × 1.4 cm = 0.98” × 0.79” × 0.55”

Main crystal size: 2 × 1.7 cm = 0.79” × 0.67”

Carrollite on Calcite

MBY69CD3: On a potassium feldspar matrix, a Chrysoberyl crystal of an intense bright lemon-yellow color, doubly terminated and with very distinct striations along the main growth axis.
The specimen comes from the pegmatite field east of Lake Alaotra, in Madagascar, and its appearance is very different from that of the classic chrysoberyls previously found in that country.

Beryl with Muscovite
 

TA62F3: A crystallographic rarity. The crystal is almost exclusively formed by the faces of at least three pyramids, while the prism is almost inexistent. One side is covered with Muscovite, which contrasts well with the deep blue-green of the Beryl. This all makes for a strongly esthetic specimen whose base is formed by the surfaces of its contact with the pocket.

TB92AL0: A new discovery at Tucson 2020. This new mineral species displays, among other notable characteristics, a dichroism: blue "Paraíba" color viewed from the front and yellow with green tints seen from the side (with focused light)
Given its hardness, color and transparency, the mineral falls into the gem category and this, together with the fact that it is a new species as well as its rarity, inevitably makes its price high. Another reason for interest is the high content of Scandium in its composition (around 3.8%)
Laurent Thomas, the person whose name the species carries, presented it at Tucson 2020 and explained to us that although the first news of this new species went out in 2018, the most important find was that of April 2019 and that is the one from which this piece comes.
