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
After a long wait the IMA have published Hubeite as a new mineral species (see IMA listing ). This mineral, which has a strong structural resemblance to Manganbabingtonite, is now officially a new member of the mineral family. To celebrate this we have looked through the stock that we have held since the specimens first appeared, awaiting this moment, and are now publishing them. As we have not seen new material for quite a while, we think that these are interesting specimens, especially as they all show good quality.

These Manganilvaites have a curious history: in the year 2002 we obtained these samples and ignoring what they were then called we analyzed them. The analysis gave as a result that it could be a new species: Manganilvaite, not previously existing. We thought to present them to be approved but we decided not to due to the complexity of the process and the conviction that some other people could be working on them. Sure nough, a little time later Manganilvaite was officially published as new species.
We re-analyzed the samples we have and we can confirm they are Manganilvaite. Now we present them on our Web. A really long way to arrive to this point!
As we normally do in these cases we will send the buyer a copy of the analysis.

EPP88ASN2: A well-known and famous association of Calcite and Stibnite from the Xikuangshan antimony deposit. The flattened Calcite crystals, though thicker than usual, show a tabular morphology with well-defined faces and edges. The crystals are very translucent, and the base contains inclusions, creating a notable interior nebula effect. Stibnite crystals coat and partially pierce through the Calcite crystal, presenting a prismatic habit with a metallic sheen and polycrystalline terminations.

MP88S7: Translucent rhombohedral crystals, very bright with an intense red color. They have very well defined faces and edges, with growth curvatures on some of their forms, and are on a matrix of rhombohedral crystals of white Dolomite. As usual with this kind of Chinese material, the matrix has a saw cut on the back side.

TB70H7: Crystal of Cinnabar of thick tabular habit and hexagonal shape. Both the faces and the edges are very sharp and bright and the crystals strongly contrast with the matrix of yellowish Dolomite. As usually happens with Chinese Cinnabars, the matrix has been sawn on the back, but not affecting, in this case, the esthetics of the specimen.

EV37K0: Sharp prismatic crystal of hexagonal shape and parallel growths. It has bright and very well defined faces and edges and strongly contrasts with the Dolomite matrix. As usual with this kind of Chinese samples, the matrix is more or less sawn, but in this case it doesn’t affect the esthetics of the specimen.

EK16I1: A beautiful miniature, of excellent esthetics due to the matrix of Quartz crystals and the luster and shape of the Fluorite crystal, but it is also mineralogically interesting for the extreme definition of the color zones in the cube, with a strong concentration of deep violet near the edges and the clear blue on corners and at the center which permit seeing the white inclusions in the crystal.

BK96C5: Fabulous luster in what if often a dull species. China has provided us an esthetic specimen of something that often is not so nice. Tabular cluster of crystals well terminated, with flat pinacoidal faces.

BB9C6: Analysis some times gives agreeable surprises, as in this case: a really sharp Tetrahedrite pseudomorphosed by Bournonite. Pretty uncommon! Plus this specimen is very well placed on its Fluorite matrix. As usual in unusual things we will provide the analysis to the buyer of the specimen.

EC64I2: The specimen is a miniature but the main crystal is of a considerable size. It has an extraordinary sharpness of its faces and edges. Also extraordinary are its luster and the presence, on the back, of growths looking like sawteeth.

TR37J7: Group of dipyramidal crystals, one of them clearly dominant, of very well defined faces and edges, an excellent luster and an unusual dark color that resembles the classic Korean specimens. The growth is not as simple as it looks at first view, and has mosaic and echeloned forms.

EA93I1: A complex group, very rich with dipyramidal crystals, bright and with very well-defined faces and edges on a matrix of Quartz crystals with Arsenopyrite and Muscovite. The specimen deserves to be in the most accredited collections due to its quality and the locality which it is from.

TR26I1: The sample is magnificent both for its size and the quality and definition of the groups of Stannite crystals on Quartz with Ferberite. The specimen had been analyzed to confirm it is really Stannite and not Sphalerite, because on Chinese samples such confusion is possible.
The specimen has been published in the book 'China', by Berthold Ottens, on page 526
