One single spinel crystal of excellent quality and intensive red color is set on a snow-white calcite matrix. The 1.1 cm crystal is sharp, well defined and absolutely brilliant! It is free of any damage! This is a superb specimen of wonderful aesthetics and very best crystal quality that has absolutely no downsides!
Wow, what a gorgeous specimen! A single 3.4 cm euclase crystal is set on a brilliantly sparkling crystallized adularia matrix! The euclase is totally gemmy and sharp and in fantastic condition. It has one intergrown adularia at the front but that is undamaged as well. The bright and shiny euclase on the snow white and all around crystallized adularia matrix makes for a spectacularly beautiful and totally pristine picture!
The main crystals on this impressive specimen are a dramatic 5.1 cm pink fluorite and a massive 8 cm aquamarine with strong blue color!
The aquamarine is highly lustrous and transparent. It is nested in muscovite but still able to show its wonderful front face as a window into its gemmy interior!
At the top of the specimen is a single beautiful fluorite. It is glassy and full of pink color with a wonderful complex surface structure.
Even at normal daylight the fluorite presents itself with strong color that contrasts with the blue aquamarine and the silvery muscovite.
Most special however is the fluorite's beautiful surface structure. Every individual part of the modified crystal displays rounded edges with fine striations which is visible down to the smallest structures which makes it no only unlikely but downright impossible that anything about this is artificial. Only nature is able to create such marvelous beauty! The whole specimen is free of damage and absolutely formidable in person!
This large hübnerite is an exceptional and dramatic specimen for sure!
The piece is composed of heavy hübnerite with sparkling white quartz.
The whole specimen is in fantastic condition and of high quality. Superb luster, sharp development and, when you add some direct downlight, flashy red color on the thinner crystals.
Hübnerite of such quality and size is exclusive to Peru and even here it has become exceedingly hard to come by! It’s an absolutely gorgeous high class specimen that really stands out!
Nice arborescent copper with a rust-brown color and a semi-matt surface. There is no damage here, not even a scratch. At closer sight it's less like a tree and more like a coral with little rounded segments, stacked up to form this lovely specimen!
The piece comes with labels from "Sammlung F. Bauer, München", "Mineralien-Sammlung Christian Rewitzer" and "Sammlung Thomas Weiland". One of the labels dates the find back to "probably shortly after 1945"
A small but highly attractive cactus-amethyst specimen from the unique finds at the Boekenhoutshoek area from twenty years ago. This lovely specimen has the intensive purple color that you would hope for, but all too rarely get! Dark, intensive and absolutely beautiful! The condition is very good with a perfectly terminated main crystal and only some minor abrasions further down. It's an appealing specimen of superb quality!
This is a spectacular Pakistani fluorite of outstanding quality and aesthetics!
The piece features a stunning etched fluorite that is 6.7 cm (!) across and totally clear! Sure, you cannot see directly through the crystal due to the vibrant etched surface but even low illumination expands through the crystal and lets it shine as if it had its own magic inner light! The fluorite shows best pink color and sits on a matrix of silvery muscovite with sheets measuring up to 1.6 cm across. There is only one tiny issue at the lower right side but which is ridiculously insignificant on a stunning and exceptional piece like this!

This amazing multi colored tourmaline crystal is grown right through a glassy shard of beautiful colorless quartz which makes for just beautiful aesthetics here! Especially as the tourmaline has such vivid colors that range from pink to green right up to the impressive golden yellow color at the sharp pointed termination! The crystal has some restorations but which is hardly visible. The overall aesthetics is really fantastic here and crystal quality is striking for sure!
It's a barite from the famous finds at the open-pit mine in Jebel Ouichane. As characteristic for these specimens the light blue barite comes as blade-like tabular crystals of great transparency and luster. They are arranged as a beautiful and three-dimensional spray. The piece is a floater with only some residual iron-oxide here and there which adds this certain natural flavor! Like an ice-sculpture this specimen reflects the light from every angle as you can easily see in our video!
This is a highly attractive schorl from the Erongo Mountains that shows uttermost perfection and very well focussed aesthetics!
The schorl itself is jet-black, highly lustrous and with a beautiful stepped growth on all sides that leads towards a pointed termination.
A ridge of contrasting white feldspar along the right side and a small group of smoky quartz crystals perched to the left side both perfect the overall picture!
Absolutely lovely aesthetics and brilliant crystal quality!
This is an unusual African dioptase that's not from Tsumeb but from the Omaue Mine south of Opuwo.
The individual crystals measure up to 1 cm in length. They are especially sharp and gemmy and lustous and with a beautiful deep green color!
They are all in flawless condition, even the tiny ones in between.
The dioptase are set on a massive piece of quartz that is naturally broken and has a coating of a pale blue mineral, probably plancheite, even on the backside.
It was found in the time between 1989 to 1991 and has been in the collection of Viennese Copper mineral collector Thomas Weiland.
Tetrahedrite with quartz and galena from the lesser known Casapalca Mine in Peru.
It has crystals up to 3.7 cm on edge which is quite stunning for the material!
The whole specimen is in exceptional condition and even the bottom is fully crystallized with white quartz.
The dark grey tetrahedrite has a layer of microscopic chalcopyrite and small calcites which adds a nice sparkling effect.
This is certainly an exceptionally good specimen for the material.
