Enstatite, variety bronzite. This specimen shows a group of intergrown crystals of bronzite, with the characteristic brassy-golden iridescence when viewed at varying angles. The effect is related to what we can see in labradorite, this specimen has a lively golden "labradorescence". A member of the orthopyroxene subgroup.

This wulfenite specimen comes from the type locality for the species and it is not very common to find specimens from Bad Bleiberg. Wulfenite was precisely renamed in 1845 in honor of Franz Xaver von Wulfen (1728-1805), botanist, mineralogist, mountaineer and member of the Society of Jesus. Wulfen is the author of a monograph on the Bleiberg lead deposits (Austria). This specimen shows us a rich group of sharp dipyramidal crystals, with small tetragonal prism faces. Some of them have complex terminal faces. The orange color and the brilliance of the crystals make it stand out on the matrix. It is accompanied by the handwritten label of Dr. Joan Viñals and belongs to the Marí-García collection.

In this specimen from the Bergakademie zu Freiberg we can see several schorl crystals, one of them with a well-defined prism and clearly visible terminal rhombohedral faces. The mica matrix contains reddish almandine crystals. Very interesting handwritten label.

Very remarkable specimen formed by several aggregates of pericline crystals, a variety of albite, well faceted, defined and with striated faces. It is worth highlighting numerous very brilliant ilmenite crystals in this specimen, with well-defined hexagonal shape. Ilmenite is an unusual species in this locality in the words of the owner of the original collection, Rudolf Hasler (Bleiberg-Kreuth). They are accompanied by groups of clinochlore and quartz crystals. It belongs from the collection of Peter Seroka (Girona), with label.

In this sample we can observe a large group of prismatic crystals, acicular, bright, with a dark violet to lavender color. The original description of this piece referred to a mineral from the amphibole supergroup called "crossite". This species is currently discredited and it is an intermediate between riebeckite and glaucophane groups. The specimens from this Austrian locality are very characteristic.

Very aesthetic aggregate of strontianite showing ciclic twinned crystals. Very brilliant, translucent and with a defined faces and edges. Accompanied by dolomite. This deposit, worked by opencut mines, in the past was also worked for talc. These specimens are a classic of the Austrian and European mineralogy.

Very esthetic "plume" formed by strontianite crystals, with parallel growths, visible terminal faces and translucent. It is disposed very aerial on a snowy dolomite matrix covered by small dolomite crystals. An European classic highly appreciated by collectors. It has a slight yellowish fluorescence under SW-UV.

Very rich group of wulfenite crystals, prismatic to tabular, intense orange color with color zoning. This specimen comes from the type locality for the species: Bleiberg, and it is accompanied by an old label: A. Bohländer, pharmacist. In the label we can read "gelbblei" or yellow lead, old name for this species. A historical specimen, from the type locality, with good size and quality... There is a very interesting article about this classic mining locality in mindat: "Collecting Minerals at Bad Bleiberg" by Rudolf Hasler.

Defined beryl (var. emerald) crystal in a matrix micasquist. The color, transparency and luminosity of beryl are quite good. It shows a defined prism with top pinacoidal faces. The specimen is significant as a locality piece.
