International Minerals #23

Great cluster of sharp, red and gemmy rhodochrosite crystals on manganese mother rock. From the classic old finds in the 1980s. They still set the standard for the species, no better quality has been found ever since.

Sharp and lustrous demantoid crystals up to 10 mm across scattered on mother rock. Ex Kurt Wintersteiger collection. No damage.

Elongated clear fluorites featuring lovely purple zones on the fringes. Small schorl crystals set a pleasing contrast. No damage.

Sharp and brilliant carrolite crystal on white calcite. Small quartzes and malachite are present as associate species. The luster of the old finds is still unrivaled, and this one is a superb miniature of the very best quality. No damage.

A sharp and glass clear selenite crystal perched on mother rock. The crystal is quite large and measures 12.6 x 3.4 x 1.0 cm. The piece is a full floater and complete all around.

Bright grass green titanite twins to 2.5 in size perched on mother rock. Superb aesthetics combined with perfect condition.

Truly red rubellites are so hard to come by, only very few localites have produced a really deep and thrilling red hue. This crystal comes from a small pocket, like the size of a football only, found about five years ago in Sahatana valley, Madagascar. Only a very limited number of crystals were recovered, and they rank among the top rubellites in the world. Little quartz crystals are attached on the sides. No damage.

Great combination of yellow, doubly-terminated mimetites resting on green smithsonites. Classic old Tsumeb stuff, no other locality has ever produced a similar number of colours and varieties of secondary ore minerals. No damage.

Golden rutile needles on brookite, preserved and included in two clear quartz crystals. Great shape and condition.

This is a superb miniature featuring two sharp blue-green cubes stacked on a bed of smaller fluorites. The piece is a true 360°-rock and perfect all the way around. Great phantoms are visible along the edges. The colours are very bright and open in daylight, there is actually no backlight needed for best display, just a white background will do it.

Clear and elongated etched heliodor crystal in perfect condition. From the recent finds.

Amazingly bright and lustrous topaz crystal, featuring crazy gemminess and sharp faces, like a cut gem. Much better brilliance in person! Ex Kurt Wintersteiger collection.
