This is a lovely pseudomorph of malachite ps. azurite, very aesthetic and showy all around! The floater matrix is covered by several dozen sparkling cerussite twins.

A chatoyant spray of Malachite set on black "glaskopf" matrix. Very rare material from an old, even prehestoric locality. First activity of the mine dates back to the last bronze age. Ex Heinrich Prager collection, his label is coming with the piece.

A water-clear, sharp and lustrous rock crystal with lots of red rutile crystals inside, a few siderites is also present. No damage.

A clear and sharp quartz crystal, 9 cm tall and 3 cm wide, standing in upright position on mother rock. White pericline crystals set a lovely contrast on the side. However, the best feature are the rutile and chlorite inclusions in the lower half, quite typical for the locality, but rarely that rich and beautiful.

Three aquamarine crystals up to 14 mm in length embedded in biotite schist matrix. The crystals show glassy character and fine sky blue color. Aquamarine from the locality represents an exceptional rarity and so it is on high relevance for the area. Ex Heinrich Prager collection.

A razor sharp terminated, water-clear rock crystal raisig up on small matrix. The shape looks like a rocket, ready for take-off. The quality is superb - the faces of the crystal show mirror luster and very attractive textures. The contrast to matrix is also very eye-catching and the piece looks wonderful in each angle. Hairy rutiles are growing up inside the crystal from the base, forming also a brownish sagenite of about 1 cm size. No damages to report, even the small crystal on matrix are in fine condition.

What a stunning bicolour tourmaline with multiple sidecars. The termination is very well formed, it shows steep angles and additional bevels at the tip. No significant damage to report.

Classic gold from California! This specimen has all the distinct features that make Californian gold so special. Brilliant luster, deep pure yellow colour, beautiful leaf and crystal structures all around. The rear side is indeed equally fine and shiny. Especially the outlines of the golden leaves are flanked by numerous sharp crystals. 39 grams of pure gold fever!

Lustrous amber-colored calcite crystals perched on thin, elongated amethyste crystals. Please note that this is very rare combination of colors and shapes, which is of high relevance for the locality. No significant damages to report.

Found in 1981, this piece comes from an exceedingly massive and rich wulfenite vein. A thick cluster of interlocking crystals measuring up to 7,5 cm across is set on a brown hematite and quartz breccia matrix. Some small contacts are present, but minor in context, and most of the crystals are in very fine condition. Malachite and other Tsumeb greens, probably duftite or bayldonite are present is some places. A great addition to every Tsumeb collection!

A well formed cluster of sharp terminated, lustrous crystals. They show a very nice contrast of colorless white and red (caused by hematite inclusions) zoning. Typically for Tsumeb, but in really fine quality. The center doesn´t show any significant damage.

The specimen shows three intergrown main crystals. Two of them vertical, the third one more at the base horizontal – this one is even double terminated. The crystals are up to 24 mm across. I think you will agree that this is a remarkable dimension of Mimetesite in dimension and color. The crystals faces are highly lustrous. The color is one more uncommon indicator, not just yellow; more intense dark orange. The assemble looks better in person, no significant damages to report. mc 2.4cm
