This page provides a selection of the specimens that have passed through the Fabre Minerals website and, due to their quality,
rarity, or significance as specimens from interesting locations, have been preserved as reference specimens in #MVM
It is a new species discovered and accepted by the IMA in the year 2005. It forms different growths, the most usual practically spherical forms, but also donut and empty hemispherical forms. This rare phosphate can be easily confused with another similar, also rare, species. So, we analyzed our samples and we’ll send a copy of the analysis to the buyer. The analytical process also confirmed that in some specimens the matrix is Beryllonite that, furthermore, appears as idiomorphic crystals which adds special interest to the specimen where it is present.

The main talking point during the Ste. Marie 2004 show was the new Hematite with Rutile from Novo Horizonte, as it was the first time that they had been seen at a European show and they were a great success. They are spectacular, some of them were on matrix, and the Rutile crystals were thicker, stronger and better terminated than in previous finds means that this find will be talked about for years to come.
We always keep a look out for new material that appears in the mineral world, so this time we were able to carefully select some examples. We looked for ones that that were perfect had had strong Rutile crystals, thus avoiding later problems during shipping.

From the famous gem Spessartine from Lavra do Navigador we are able to offer these specimens. We selected them primarily for their good transparency, and also when they have brilliant crystals that are well defined. We tried to avoid the ones that have a ‘dissolved’ look, which many of the ones from this find show.

TM36D8: From the famous find of gem Spessartine from Lavra do Navegadora we obtained this enormous crystal that shows of all the great features of the find. Intense color, great transparency, a floater, complete and with dissolution marks on its faces. In this piece, just to add to everything else, the brilliance is extraordinary and, even though it is quite thick, the gem quality of the crystal is very visible when lit from the front and spectacular when lit from the rear. There is a little bit of Albite on this powerful specimen.

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.

TK6K9: On the same specimen there are two very rare species. Beige crystals of Kosnarite with pinkish, radial aggregates of Zanazziite, on white Albite matrix. The Zanazziite has been carefully analyzed and the result is surprising: iron is nearly replaced by manganese (thus its pinkish shade), so we present it as manganoan Zanazziite. Matrix is Albite. We’ll send a copy of the analysis to the buyer.
