An unusually large and well-covered plate of electric blue, neon almost, aurichalcite crystals. Old material! 9 x 7.1 x 1.4 cm
Nestled in a vug with tiny, colorless hemimorphite is the most beautiful diverging spray of light teal blue aurichalcite. The acicular and radiating crystals of aurichalcite are bright and lustrous AND relatively LARGE, among the best you could ask for for the species. 4.7 x 2.8 x 2.5 cm
A rich rolling carpet of botryoidal Aurichalcite, from a locality better known for blue smithsonite in such richness. This is, indeed, a rare and rich example for the mine. 5.3 x 3.8 x 1.4 cm
6.6 x 4.8 x 3.2 cm. Light aqua colored sprays of acicular aurichalcite abound on this matrix specimen. The individual crystals are both lustrous and gemmy. The aurichalcite is very reminiscent of that from the Kelly Mine in New Mexico. The matrix, however, is very distinct and unusual. This is a stellar locality piece that also happens to be aesthetic in its own right. Tim Blackwood Collection.
A beautiful and aesthetic Arizona aurichalcite specimen from the famous 79 Mine in Gila County. Clusters of radiating turquoise-blue aurichalcite needles rest on sparkly, quartz on matrix. This piece may be from the famous late 60s-early 70s find by Mineralogical Record publisher Wendell Wilson, generally considered to be the finest in the world for the species. 6.8 x 5.0 x 2.6 cm
A STRIKING and RARE specimen from Mina Ojuela of lustrous, robins eggs-blue aurichalcite needles attractively lining a vug in contrasting limonite matrix. Common in the 1960s, but to quote the Mineralogical Record Special Issue on Mina Ojuela (Sept.-Oct., 2003) aurichalcite, "it is a rare mineral on the market today." Old dealer stock of Dr. Gary Hansen and not shown since the early 1980s! Ex Smithsonian Collection. 6.0 x 4.6 x 4.2 cm
A MOST UNUSUAL and excellent two-sided crust of aurichalcite from the famous Kelly Mine of New Mexico. One side looks like a cluster of banded, powder-blue garlic cloves, while the other side is the more characteristic, botryoidal, deep turquoise-green form. Choice and uncommon material from an old find 2.8 x 2.5 x 1.0 cm
Velvety, sparkling acicular crystals of an intense blue-green, in clusters scattered across the limonite matrix. Aurichalcites have one of the prettiest colors in the mineral kingdom, in my humble opinion. From the classic Ojuela locality. 8.1 x 5.4 x 3.2cm
A very showy, CABINET-SIZED plate, richly covered with radial clusters of robin"s egg-blue, acicular aurichalcite crystals on a nicely contrasting gossan matrix from a classic, old-time Utah locality, the Kesler Mine in Big Cottonwood Canyon. Ex Seaman Museum Collection. Never seen such a good one up for sale4 before this piece which I traded out of the Museum a year or so ago 14.5 x 9.5 x 3.0 cm
A druse of sparkly quartz adds pizzazz to the robins-egg blue aurichalcite, which in fact is a densely-packed layer if millions of acicular crystals. 9.3 x 7.1 x 5.1cm
The pocket on this specimen contains lustrous crystals taupe-colored hemimorphite with balls (most of them partial) of velvety aurichalcite (consisting of thousands of needle-like crystals growing out radially to form balls). 8.9 x 5.5 x 4.0cm
This specimen features a matrix coated with a beautiful layer of pastel, aquamarine colored, acicular aurichalcite , blanketed with colorless, lustrous calcite crystals, to 1.0 cm across. Classic and rare today, on the market, these are selling at a premium when they do turn up and make for unique locality pieces. 5.3 x 4.6 x 2.9 cm
Look at the beautiful patterns of snowflake-like platnerite against a backdrop of deep green aurichalcite on this limonite matrix! A rich and pretty old Mapimi combo specimen! 7.9 x 7.9 x 4.9 cm
A pretty "cutie" of aurichalcite from a mine much more famous for its smithsonites - and in fact, these were not common from there! This one came out of Sam Nasher''s noted thumbnail collection. 2.2 x 2.0 x 0.9 cm
Spheres of matte, teal blue aurichalcite, to .8 cm across, is emplaced on vuggy limonite. In addition, there are a few rice grain crystals of translucent, lustrous, light blue smithsonite. Rare combo! 5.7 x 4.3 x 2.4 cm
