International Minerals #29

Lovely nests of Gold perched on goethite, quartz and mother rock. Ex Hilde Könighofer coll.

Nicely isolated balls of shattuckite resting on a matrix of goethite and quartz.

Two sphalerite crystals featuring nicely stepped growth patterns, resting on a bed of dolomite crystals. Floater piece, complete all around. Both crystals are gemmy and glow fiercely orange when backlit. Ex Alfred Haas coll.

This is a wonderful floater specimen, complete and well crystalized all around, showing several ball shaped aggregates of azurite on contrasting malachite. The picturen shows what I consider the rear side, but again, it displays beautifully from either side.

Wonderful clear yellowish sphalerite crystals and minor galena on rhodochrosite. Ex Alfred Haas coll.

Dozens of hutchinsonite crystals up to 8 mm in length, auripigmente and barite crystals scattered on a mother rock made of pyrite and quartz. Ex Zatsch Mineralien, ex Hilde Könighofer coll.

Two elongated afghanite crystals in marble, a couple pyrites add a nice sparkling contrast. Ex Oliver Konczer coll.

A wonderful clear calcite aggregate featuring multiple twins on a matrix layer of barite and pyrite. No damage. Ex Alfred Haas collection.

A strong twinst and an interesting mix of frosted and glossy faces make this piece truly special. The clarity is excellent, and the colour is a pleasing light smoky hue.

Several atacamite flower rosettes up to about 4 cm in diameter resting on a nicely contrasting mother rock. Definitely one of the best specimens I have ever seen of this style. Ex Alfred Haas coll.
