This rare and unusual pseudomorph of chalcedony after barite comes from the Henry Mountains in Utah. The specimen is nicer than most consisting of sharp replacement and brownish red translucency without damage.

Considerably showy. Wow, the lush green of malachite stands in sharp contrast to surrounding fuchsia pink cobalt-rich calcite. This is older material from this world-renowned locale and would make a colorful addition. Ex Rosa Nowels collection
For more than a century fine specimens have come out of Butte’s dozens of mines, with the Leonard producing some of the choicest material, such as this neatly stacked cluster of pyrite. A Gene Schlepp specimen before ending up in the collection of Rosa Nowels.
Extraordinary for Tantara and one of the best of its kind. This is the only place where such exotic combinations occur together in splendid examples. The rarity lies in unexpected crystals of dioptase on replaced calcite. More precisely, this pseudomorph is layered with malachite over a layer of dioptase, and the entire replacement itself is after calcite. It is a superbly composed specimen with excellent aesthetics, for these modern classics in the making. Ex Rosa Nowels collection
Pleasing violet-purple fluorite from the Denton mine in Illinois. Undamaged, entirely transparent and slightly frosted in complete coverage lining a nearly flat plate. Great display specimen and an American classic.
Choix must have the most pleasing botryoidal pinks, such as this isolated full sphere of extreme botryoidal growth that is by far its best feature. Glistening silken pink color free of any surface damage. Ex Rosa Nowels collection
Individual prehnites, pierced by doubly terminated epidote, reach between 1 and 2 cm. It seems unusual in that they are so well defined and clearly show it. Formerly in the collection of Rosa Nowels.
Typical of the 1947 find from the 1300 level of the Campbell shaft. This Bisbee pseudomorph has managed to retain the shape of the original crystal in a way that is not at all rough. This is historic, old-time material from Bisbee. Ex Rosa Nowels collection
Stunning wulfenite with the glassy shine and quality characteristic of Red Cloud mine, Arizona. They are orange to red throughout, very sharp and super bright.
Fine small cabinet piece of 8 x 6 x 3.5 cm from Power’s Farm, Pierrepont, St Lawrence Co., New York. Add to that a desirable historic locality and source of good dravite specimens since 1830.
