A choice, lustrous single prismatic Epidote crystal from the famed Vaux collection, #5961. Good thumbnails like this are rare from that era and this is in excellent condition, very clean and complete all around. The label dates this to March 1892 when it was acquired. The habit is not the elongated type usually associated with Untersalzbach but a thick, stout crystal with pronounced striations.
An elegant, very well crystallized Strontianite from the classic locale of Oberdorf. This cluster is a floater- it is crystallized on all sides and shows two differnt habits probably formed in two generations. The individual crystals reach almost 3 CM and the condition is impeccable, with no damage to be seen. Displays very well from almost any angle, each side is very presentable. The recent detailed Mineralogical record article gives an excellent view of this remarkable deposit and the great Strontianites there. Excellent value for a choice display quality classic specimen.

Oberdorf an der Laming, Laming valley, Bruck an der Mur
6.8 x 6.3 x 2.9 CM (cabinet)
Complex, perfectly formed clusters of Strontianite crystals from Oberdorf. The better old Styrian Strontianites like this are considered to be the best for the specie. Sharp, free standing hexagonal crystals up to 1.5 CM and are in perfect condition. This esthetic piece shows the septums and thin walled cast structures that hold the Strontianites by very tiny points of attatchment. This is from the collection of Terry Szenics and retains his label. The recent Mineralogical record article explains very well the locality and specie. An excellent specimen of a common mineral that is not often well crystalized
A very old (18th century) Tyrolian Garnet specimen from the Zillertal. This area has been the source of Almandine for centuries, these were sold and traded worldwide. This comes with an early Julias Bohm label and a much older (crumbling) one as well as an affixed one on the specimen back. The matrix is an unusual one, a complex mix with Actinolite, Hematite, Magnetite, Quartz and more unusual, small Galena and other Sulfides. Not the usual mica Schists we typically see from the Tyrol. The main crystal is well exposed and complete 1.5 CM in diameter and has some good translucent areas.
A large specimen from Bleiberg (Type locale) that is mostly Hydrozincite some formed over and with Smithsonite. Very well defined bothroids on a cast of Gossan that has additional layers of Hydrozincite seen on the underside. In fine condition, fluorescent and with some luster. One old label included mentions only the Smithsonite. For what is often an un attractive mineral specie, this is quite attractive and well composed.
Magnesite- large crystals

Worldwide mix summer
Very large to 5.6 CM across Magnesite crystals clustered on a Magnesite matrix from this classic locality. Kaswassergraben is famed for these rare and unusual hexagonal crystals unlike any other locality. This is an excellent example of a rare matrix piece with huge crystals for the locale. The back side is broken from the host rock but the front side main crystals present well with a fine pearly luster and stepped growth faces. I have not seen many of these and this is by far the largest crystal cluster I know of, other large crystals are usually about 2 CM at best.

An esthetic, old Garnet specimen with crystals to 2.8 CM in impeccable condition. What sets this piece apart is the rich red color and translucency, which is far better than most. Well presented and exposed in a nice composition. As is often the case with these Austrian classics, there has been a thin layer of clear shellac or varnish applied which stabilized the often crumbly Schist matrix and adds a little luster to the garnets. This is now seen as an undesirable tactic but in the 19th century it was common. This can be removed with Acetone if desired but it is historicaly accurate to keep it as well.
A classic Tyrolian Andalusite, several sharp crystals are well exposed from enclosing Quartz. These old Austrian specimens are some of the best examples of this specie, which is usually not very impressive. This is in fine condition and has strong esthetics. With several old labels, this is a about as sharp and perfect as these crystals get.
