Druse of small prismatic brilliant olivenite crystals, olive green in color, transparent to translucent. They stand out on the quartz matrix. From this classic French mine. It belongs to the Joan Astor collection (Barcelona), with a handwritten label and another typewritten.

Galena crystal on fluorite from Fontsante. The cube crystal is truncated by octahedron faces. It shows a bluish color due to the natural iridescence. Perfectly disposed on a fluorite matrix covered by brilliant small quartz crystals. It was collected in the Saint-Augustin vein (known for its sulphides). It is no easy to find samples with this quality from this French locality. This former fluorite mine started works in 1919 and closed in 1987.

This aesthetic specimen shows a very rich group of acicular cyanotrichite aggregates, with a deep blue color and brilliance. They're accompanied by green globular aggregates of parnauite. Also we can enjoy groups of green-blue hexagonal chalcophyllite crystals, perfectly defined. The matrix is covered with different iron arsenates. A piece of a classic French mine where today is impossible to get specimens, and less of this quality.

Very rich group of azurite crystals, with deep-blue color and very bright. Disposed on the matrix as isolated crystals or in rosettes. Good luster and transparence. Observed under the microscope they show an excellent composition. This specimen is from a classic French mine: Cap Garonne. This mines are well known for the rich paragenesis of rare species. Today it is impossible to collect specimens as closed as mining museum.
