Very good size crystal of benitoite, a rare barium and titanium silicate, rich in faces, highlighting those of the trigonal dypraramid, together with those of the hexagonal dypyramid and the pinacoidal faces. Intense color and translucent. It has a small dent in one edge, common in these specimens without affecting the aesthetics of the specimen. On matrix.

Type Locality

Good sized hydromagnesite specimens from this mine and with this quality are uncommon. On the rocky matrix, several globular aggregates of transparent crystals, with a white aspect. Brilliant and very rich specimen. Specimen originally in the collection of Hubin (Belgium).

Size: 8.5 x 6.5 x 4.0 cm.
Main crystal: 3 mm glob.

A specimen for systematic collectors... A large group of needle-like colorless crystals (prismatic) of artinite, forming aesthetic rosettes. But in this sample we highlight some aggregates of desautelsite crystals, a rare manganese and magnesium carbonate found in very few locations. They are orange crystals forming groups together with the artinite.

Size: 4.3 x 1.6 x 1.8 cm.
