Tetrahedrite (silver rich variety) with Chalcopyrite and Quartz.
MB91AG1: Tetrahedrite (silver rich variety) with Chalcopyrite and Quartz
This elegant silver-rich Tetrahedrite with Chalcopyrite and Quartz has a long history with labels starting in 1925 by Franz Ding and ending with John S. White. At that time the silver-rich Tetrahedrite was called "Freibergite", that name has come with the label but an analysis have proven that it is not "Freibergite" but silver-rich Tetrahedrite. Although the photos may look like there is a broken crystal the piece is perfect and has no damage. We will send labels and the analysis to the buyer of the specimen.

Titanite on Rutile after Ilmenite and with Microcline.
SM150ERG: Titanite on Rutile after Ilmenite and with Microcline
Lamellar Ilmenite crystals with an irregular outline were completely replaced by Rutile and covered by very sharp Titanite crystals. They show great luster and very well defined faces and edges, with a distinct color change that shows an intense yellow under LED light and greenish under natural or fluorescent tube light. The process of substitution of Ilmenite by Rutile here seems very similar to that already known in other locations with similar geological conditions (for example the Rutile from Zambia) and is due to hydrothermal processes associated with the deposit. These specimens, very different from the titanites previously known from Imilchil, have undergone urgent analysis that we plan to continue to carry out in more depth. We will send the buyer the information and documentation obtained so far, as well as a copy of the analyses carried out on the species present in the current specimens.

TC180ET: Titanite on Rutile after Ilmenite and with Microcline
A novelty at Sainte Marie-aux-Mines 2016. Platy Ilmenite crystals with irregular contours and completely pseudomorphed by Rutile, coated by very sharp Titanite crystals that are bright, with very well defined faces and edges, and with a very apparent pleochroism that shows a yellow color under led light but is greenish with daylight or neon light. Partially coated by Microcline crystals. The process of replacement of Ilmenite by Rutile seems very similar to that of other localities with similar geological conditions (by example the Zambian Rutile) and it is due to hydrothermal processes at the site. We’ll send to the buyer a copy of the analyses done on the different species present in the samples.

The process of replacement of Ilmenite by Rutile seems very similar to that of other localities with similar geological conditions (by example the Zambian Rutile) and it is due to hydrothermal processes at the site. These samples, very different from the Titanite previously known at Imilchil, have required a hurried analytical process that we’ll extend and complete. We’ll send to the buyer the information and documentation previously obtained about the process and also a copy of the analyses done on the different species present in these samples.
