Highly unusual but staggeringly appealing, this is a perfect azurite aggreagate of high quality. At the lower parts and expecially at the side the crystal is somehow erroded but which makes for a completely unusual appearance as I have not seen alike. Some brown crumbling matrix adds more contrast to the dark, lustrous and gemmy blue azurite. There is no damage here, even the bottom is all natural. An outstanding specimen, perfect on all sides.

Beautifully rounded crystals are forming a 3-dimensional sculpture of bright golden color. This unusual crystal shape is a transition of pyritohedron and octahedron which is quite rare even for Huanzala standard. The surface is mirror-bright and golden on all sides with nice striations. The whole piece is in excellent condition with only minor, insignificant issues. A perfectly aesthetic pyrite of highest quality!

Colorless quartz gwindels are actually harder to find in the Alps than are smoky quartz gwindels. Fortunately in 1987 the famous Marmottakluft produced this great matrix piece, being a rarity even to this cleft. The nearly closed gwindel is of exceptional luster and clarity. Being perched on a beautiful matrix among high quality side crystals we can honestly say we are dazzled by this specimen. There are two smaller chips at the backside, being hidden for the jagged crystallization und thus not visible from the front. The rest - even the side crystals - is just perfect. The brownish matrix holds a couple of tiny anatase crystals, is naturally broken at the bottom and a fittingly pretty base for this pristine crystal. The solidification of a real "wow" factor!

This is exactly the rich cherry-red color fluorite from frunthorn are known for. Seeing two of these crystals - the larger of which is nearly 3 cm on edge - on a beautiful piece of matrix leaves me marveling, especially as there is not a single flaw in sight. The characteristic wheathered granite matrix provides a beautiful sparkling basis and makes this a outstanding Alpine specimen. Watch the video for a better impression of the 3-dimensional quality of this wonderful piece!

A compelling landscape of dark brown smoky quartz and snow white adularia crystals on matrix. It is a piece of stark contrast, like quartz and adularia fighting an everlasting war for attention. Both minerals are well balanced, none is getting the upper hand. In between those fronts there is some associated chlorite and byssolite to fill the gaps. An impressive piece of high quality, free of damage and full of lovely details spread all across the massy, natural matrix.

This brownish orange crystal with neon-yellow core is in fact a hybrid of ettringite and sturmanite, forming this dramatic piece. As a single crystal on dark contrasting matrix, the impact of this very rare specimen is exceptional. The hexagonal shape of this flawless sturmanite is nicely discernible all around and even shows faces at the bottom like on a doubly terminated crystal. We luckily got this piece out of an old collection as there is not much new comming these days. A rare chance for an excellent strumanite/ettringite specimen!

About 1 km south of the Knappenwand and its famous epidote is the Popberg, home of these classy adularia crystals. Several adularia crystals of superb quality, gemmy, lustrous and partly covered in some chlorite, are perched on a brilliantly sparkling piece of matrix. The backside is naturally broken and even shows some lovely crystallization. This is a piece of great aesthetics, where the chlorite adds color and contrast just in the right amount. Marvelous quality, perfect proportions and no damage on any of those great adularia crystals!

A filigree sculpture of pure white adularia that is a complete floater. The adularia is highly lustrous and of great translucent quality. Spread over it is a rather small amount of green chlorite adding a nice Alpine character without disturbing the beauty of this lovely piece. Remarkable and in perfect condition!

The famed purple color of Zogno fluorite is absolutely mesmerizing at this unusually well shaped piece. Most pieces are so heavily etched - which is not per se a bad thing - that the original habit is unrecognisable. Here on the other hand the cubical shape is obvious with amazing 9.3 cm on edge. Bottom and backside are more heavily etched and gradually the shape turns into a more typicall Zogno fluorite. Best color is at the bottom of the crystal so a low backlight illumination would bring out this flash of purple color in the most favorable way!

The quality of this piece is hard to put into a photograph so I strongly recommend our video where clarity and luster are much better discernible. This smaller gwindel is half closed which is extremely rare. Except for on minimal ding this piece is flawless and even at the bottom, where it detached from the matrix it is nicely crystallized. Inside the crystal there is not a single crack! A brilliant piece of marvellous quality that is much better inperson!

3-dimensionally arranged acicular rutile needles on tabular hematite, characteristic for the famous locale of Novo Horizonte. The straw-yellow rutile is in surprisingly good condition and remarkably beautiful. Outstanding for its lovely aesthetics and the relatively large overall size.
Please note: Due to its fragility hand delivery is a must at this specimen. Please contact us, so we can arrange a meeting!

Thick and glassy, sparkling and dominant, this impressive quartz specimen from Felbertal is absolutely amazing! The main crystal, over 18 cm long and 7.4 cm in diameter, is of best quality with a completely glassy upper half, sharp edges and great weet-look luster. The backside is contacted - though perfectly re-crystallized - and in some parts covered in beautiful dark green chlorite as is characteristic for the locale. The whole piece is in excellent condition with only some insignificant edgewear. A marvelous quartz specimen, large and impressive!
