Numerous groups of prismatic willemite crystals in the cavities of this matrix with galena, siderite, quartz and goethite. The crystals show hexagonal shapes truncated by pinacoidal faces, they appear isolated or forming aesthetic stars. Some of them are dotted with rhombohedral crystals, between honey-colored to greenish, of siderite. Fluorescent under short wave UV light. A good size specimen of this classic Occitan Pb-Zn mine.

A very rich specimen formed by several aggregates of acicular to prismatic pyromorphite crystals with an intense green color and silky luster. On a rocky matrix. A French classic from old "times".

Botryoidal aggregates formed by goethite microcrystals, with a delicate velvety appearance with deep brown to black color zoning. In section we can observe the radial arrangement of goethite crystals. The matrix is a mixture of goethite with some siderite rhombohedrons. These specimens are from a find in the Mont-Roc mine, that is known for the French mineralogy for its brilliant goethites and fluorite.

Botryoidal aggregates formed by goethite microcrystals, with a delicate velvety appearance with color zoning that varies between brown garnet to dark gray. In section we can observe the radial arrangement of goethite crystals. The matrix is a mixture of goethite with some siderite rhombohedrons and quartz. These specimens are from a recent find in the Mont-Roc mine, that is known for the French mineralogy for its brilliant goethites and fluorite.

This specimen shows stalactític aggregates of rhodochrosite with a pink color. They are accompanied by brilliant botryoidal kentrolite, with a deep black color. It is a rare lead and manganese silicate. Nice specimen for the species and dedicated to systematic and French collectors.

A specimen very rich in aggregates of acicular prismatic  pyromorphite crystals with an uniform green color and silky luster. On a quartz matrix. A French classic from old "times".

A specimen very rich on aggregates of acicular prismatic  pyromorphite crystals with an uniform green color and silky luster. On a quartz matrix. A French classic from old "times".

A specimen very rich on aggregates of acicular prismatic  pyromorphite crystals with an uniform green color and silky luster. On a quartz matrix. Good display size. A French classic from old "times".

Group of very sharp fluorite crystals showing cubic forms and trapezohedron faces on some vertexs. Well defined faces and edges, transparent to translucent. Yellow color is uniforms, with curious internal colorless structures, and some siderite crystals on them. A huge size specimen from this French mine.
