The allanite-(Ce) specimens from Trimouns are a classic of French mineralogy. It should be said that if these crystals are analyzed compositionally, a zoning with dissakisite-(Ce) is observed. Both species belong to the epidote group and are compositionally differentiated by the presence of Fe(II) (allanite) and Mg (the second). In this specimen we can observe several well-defined crystals of this mineral, one of them larger, which contrasts with the dolomite matrix.

Very exceptional group of bastnäsite-(Ce) crystals. Good size, defined faces and edges, transparence, brilliance... And perfectly disposed on a dolomite crystal matrix with talc. A rare opportunity to obtain a top quality specimen of this REE carbonate from this classic French talc quarry.

This specimen is showing a very rich group of allanite-(Ce) crystals, disposed randomly on a cavity covered by dolomite and calcite. This mineral with Rare Earth Elements (REE) is a classic for this French quarry, in the Pyrenees. It shows very elongated prismatic crystals, with transparence and brown to toasted honey tones.

Exceptional hyaline quartz crystal showing a developed prism with marked horizontal striations on faces and excellent terminal rhombohedral faces. Very sharp, perfect transparence anb best brilliance. Acompanied by a small matrix with dolomite rhombohedra. Specimen is better on hand than in pictures. This sample was collected from the dolomitic vugs of the Trimouns Talc quarry.

A single and sharp crystal of bastnäsite-(Ce) showing tabular hexagonal shape. They show a good transparency and color that varies between yellow-green to orange-brown, depending on the type of the light that strikes them. Accompanied by corroded allanite-(Ce) as usual in this paragenesis. This specimen is from a French worldwide classic mine for Rare Earth Elements (REE) species: Trimouns. Currently it is not easy to find bastnäsite-(Ce) specimens from this mine and with this crystal size.

Gem quality allanite-(Ce) specimen, with a good size, elongated and showing well defined faces and edges. It is embedded in the matrix of calcite with brilliant talc. Transparency and luster are excellent and shows a zoning toasted honey color, with green pleochroism visible depending on light. It is accompanied by other smaller crystal similarly defined and transparent. The area where I extracted no longer exists, when quarry has been extended. A piece of Rare Earths (REE) of a classic French locality, aesthetic and not easy to be found nowadays.

This specimen is from a worldwide classic mine for Rare Earth Elements (REE) species. We observe two groups of defined tabular hexagonal crystals with small pyramidal faces. They show a good transparency and color that varies between yellow-green to orange-brown, depending on the type of the light that strikes them. Currently it is not easy to find bastnäsite-(Ce) specimens from this mine and with this crystal size.
