This lovely fluorite specimen shows brilliant crystal quality and beautiful aesthetics! The single 1.6 cm fluorite is exceptionally glassy and has that distinctive green color with dark purple around the edges. It is complete all around, no damage. The fluorite is set on a piece of white microcline with fine needles of black schorl all over it. Some of the schorl is even intergrown with the fluorite but not too much to disturb the beauty of it!

A brilliant classic tourmaline from Minas Gerais that is exceptionally glassy and brilliant! The colorplay is something amazing as well. There is rare orange at the lower half that gives way to yellow and green towards the termination. The termination itself is complex and pointed, although somewhat rounded due to etching and erosion. The whole specimen has a somewhat weathered look but which does not distract from the high quality and beauty of it! There are some small abrasions present but no repairs or fills. A dramatic specimen with an impressive visual impact!

This stunning specimen was part of a small find of skeletal quartz crystals in 2023 and it is by far the best of the lot! With a size of 14.2 cm and water-clear quality it has a splendid showcase presence! The quartz is complete and undamaged and shows vibrant luster all around. The etched surface has a beautiful structure. You can still identify the original hexagonal prismatic shape but it is heavily dissolved on all sides which looks just spectacular! The inside is completely limpid like spring water!

This is basically a single 3.2 cm long crystal with some associated matrix. It is classic fibrous green brochantite but with a well developed termination and hardly a scratch anywhere. The piece comes with a label from Donald K. Olson.

This fluorite strikes with intensive emerald-green color and a dominant elongated main crystal.
The whole piece is in fact a massive fluorite cluster with a very well developed individual crystal in best condition at the top.
What is extremely attractive is the striking color of the fluorites.
The core is of the most intensive and beautiful green, towards the outside there is a colorless zone which encases the green like glass around a green liquid.
Absolutely beautiful in person!
The fluorite is well developed, lustrous, nicely structured and transparent.

This piece is a really exceptional and highly attractive paragenesis of nice red rhodochrosites on white quartz, as well as grey galena and golden chalcopyrite.
It is really beautiful how the galena and chalcopyrite concentrate on the right half, while quartz is dominant on the left.
The rhodochrosite crystals show superb luster and clarity and have elegant raspberry red color.
A lovely specimen in very best condition.
The piece comes with a label from Austrian dealer and collector Wilhelm Niemetz who had the piece in his private collection for many years.

Most striking about this unusual brucite is the unique shape that instantaneously reminds me of a well crafted, elegant tobacco pipe.
It is a piece of pure brucite with only residual rock matrix at the backside. All the rest is just shiny, well crystallized and intensively yellow brucite!
In fact the color is quite amazing. Many specimens have a much paler yellow to almost white but this one shows quite the color you would be looking for in this fine material!
However you turn this piece you can’t find any damage. Everything is perfectly crystallized, right up to the small extensions at the top (the “mouthpiece”, if you follow my picture of a pipe).

That deeply red single crystal on white matrix is a fantastic sight in person. Even at first impression you can immediately say that it has what others lack: The gemminess, the luster and - most of all - the ruby-red color that everyone is so crazy about! With a main body length of 1.1 cm it is not exceptionally large but quality always outdoes size, especially on the famous gemstones of this world. Absolutely beautiful and incredibly well developed!

Three characteristic prase crystals are nicely arranged with some hematite attached to the leftmost crystal. At first glance that crystal might look damaged but in fact that’s just because of the intergrown hematite which caused the growth irregularity. The quartz itself is completely undamaged. The hematite at the very left is a half developed iron rose. But also this is not broken but covered in some iron oxide. It's all natural and fine.

This piece has a very well defined composition. A 4.4 cm long main aquamarine is running through a piece of nicely crystallized white feldspar with some addition of mica and beryl micro-crystals.
The aqua is doubly terminated, glass and with a lovely blue color.
There is a second, thinner crystal at the back which is a bit longer and thus stands out at the top. This is also well terminated.
Only at the back of the aquamarine there is a damage where a third crystal used to be. This damage is not visible from the front though.
Aesthetics and quality are really excellent here!

The piece is from the famous find in 1991, which arguably yielded the best rhodonite specimens of Peru. We got the specimens from the private collection of Helmut Brückner in Germany, a label is included with the piece. It has a total size of 4.8 cm with individual crystal up to 2.2 cm. It is a complex and most attractive cluster of bladed rhodonite with small sphalerite and calcite in between that is in surprisingly well condition. Brilliant crystal quality is what makes this specimen impressive and exceedingly rare!

This hematite from the Alpine type clefts of Pakistan shows a single well defined aggregate, studded with rich rutile crystals. The hematite is set on a well crystallised cluster of scalenohedral calcite with chlorite. The backside is an equally nice wonderland of hematite, rutile, muscovite and calcite, fully crystallised and flawless. A lovely floater specimen of distinctive Alpine character.
