Beautiful white calcite balls isolated and in groups on nicely contrasting siderite matrix. Very 3-dimensional and nice from all sides. No damage.
Thick and sturdy silver curls on nicely contrasting calcite and siderite matrix. An old label indicates the piece was sold by Prof. Dr. Siegmund in 1959. For sure not a fake!
Sharp and well formed azurites, partially altered to malachite, forming a very balanced cluster. Great shape and condition!
Deep purple fluorite cubes, each of which is featuring an amazing phantom, on nicely contrasting quartz matrix. A large and well formed barite rose sets another beautiful accent. All the edges of the fluorites are very sharp and free of damage.
Highly lustrous sphalerite ball perched on artichoke quartz. The quartz crystal is well formed on all sides. Pristine condition.
A spray of iridescent berthierite is crossing a group of sharp and clear barite crystals. Great composition and form! There is one minor contact on the rear side, otherwise the specimen is in excellent condition.
Gorgeous etched bi-colour fluorite from Zogno! The colours are lovely, and the composition is just striking! No damage. Ex Robert Brandstetter collection no.677, his label is still coming with the piece.
Superb, sharp and large proustite crystals in a composite cluster group! The colour is pure deep red gem when backlight from top to the very bottom of the specimen! Note that only a part of the crystals were backlight for this picture. Minor chipping is present on a side crystal, but the damage is easily forgivable considering the size, the impact and the historical importance of that specimen. Truly a masterpiece from this old German locale! Ex Hubert de Monmonier collection.
Wonderful boulangerite included calcite rosette. Stepped faces, shiny luster and an overall floater form, great features to make a lovely specimen!
Gorgeous dyscrasite thumbnail specimen featuring unusually large and sharp crystals! Undamaged and well formed from all sides!
Great miniature from this old and defunct locale! Sharp barral-shaped crystals form a lovely crystal cluster. Great aesthetics and condition.
Sharp and lustrous acanthite crystals on quartz matrix. Tiny pyrites and hematite inclusions set a nice contrast. Great classic specimen, very hard to obtain any fine specimens from this defunct locale.
