9.5 x 7.2 x 5.3 cm. Radial aggregates of lustrous, blue-green blades and hackly microcrystals of aurichalcite richly cover the sculptural matrix on this fine, old-time piece from the less well-known Bristol Silver Mine of Nevada. Rich, highly representative and seldom available material from this locale. Ex. Robert Jenkins Collection.
9.0 x 8.0 x 6.5 cm. The Mina Ojuela has produced a new find of this beautiful and striking combination material. Glassy, transparent calcite rhombs to 1.8 cm across are richly and aesthetically strewn in a sculptural vug in starkly contrasting, sturdy gossan matrix. The vug is lined with beautiful, robin’s-egg-blue aurichalcite. Some of the calcite rhombs are included with aurichalcite and some are not, which really adds to the attractiveness of this fine piece.
Sparkling balls of needle-like crystals, of a gorgeous blue-green hue, against a contrasting matrix around the rim - from the very desirable old locality of the 79 Mine. 3.9 x 4.3 x 2.4 cm
12.5 x 10.0 x 1.5 cm. The Mina Ojuela has produced beautiful and striking combination material. Glassy, flattened, colorless calcite rhombs comprise this thin cabinet crust, which is richly and aesthetically included with beautiful, robin’s-egg-blue aurichalcite. Some of the calcite rhombs are included with aurichalcite and some are not, which really adds to the attractiveness of this fine piece. Pieces of this quality came out in the mid-1960s, with none since. Ex. Mullane Collection.
6.7 x 2.8 x 1.8 cm. Four bright blue-green tufts of acicular crystals of the copper-mineral aurichalcite, from the 79 Mine in Arizona. The crystals are like little starbursts of fine needles aesthetically perched on the sturdy, layered, vuggy, box-work matrix. Scintillating hemimorphite microblades festooned on the matrix are a super accent. The small vug lined with olive-green smithsonite crystals is a real bonus and is very uncommon. Ex. Jaime Bird Collection.
7.3 x 5.1 x 4.5 cm. A very rich specimen of these secondary copper minerals for the locality. Usually both minerals occur as small acicular crystals or, worse yet as smears, stains, or blebs here and thus not as mineral specimens per se in their own right. This is a really rich piece though, with lighter blue-green aurichalcite over a rich massive growth of the brochantite. Harold self-collected this in 2003, when he was well into his late 70's. Ex. Harold Urish Collection.
8.9 x 7.0 x 6.9 cm. This is a gorgeous and unusual piece. It is a complete hollow vug, or pocket, filled with a soft carpet of rounded aurichalcite. It is just plain pretty. Such things just do not usually survive and come out intact, and this is a great way to see how such minerals form in the mines, in their pockets. Minor little red specks inside are wulfenite, as a bonus. Ex. Harold Urish Collection.
10.5 x 8.7 x 4.5 cm. A beautiful and large plate of sparkling, hair-like aurichalcite crystals, richly covering a layered piece of matrix. Although the mineral is well known from the locality, large plates like this are uncommon. Purchased in 1980 at the Tucson show, according to his notes. Ex. Harold Urish Collection.
4.3 x 3.8 x 1.6 cm. This is an unusual specimen for its color, consisting of minute calcites richly included by aurichalcite. Ex. Harold Urish Collection.
9.3 x 7.9 x 4.6 cm. The Mina Ojuela has produced a new find of this beautiful and striking combination material. Glassy, transparent calcite rhombs to 2.6 cm across are richly and aesthetically strewn in a sculptural vug atop starkly contrasting, sturdy, banded, gossan matrix. The vug is lined with beautiful, robin’s-egg blue aurichalcite needles. Some of the calcite rhombs are included with aurichalcite and some are not, which really adds to the attractiveness of this fine piece. A stunning new find.
11.5 x 9.9 x 5.4 cm. A remarkable, richly crystallized cabinet aurichalcite specimen from the Mina Ojuela of Mexico. Radiating clusters of glassy, beautiful turquoise-blue aurichalcite needles fill the sculptural, vuggy, limonite matrix. Green rosasite coats some of the aurichalcite on the upper-left and lower-right side fringe. An added bonus is more aurichalcite in a vug on the side of this outstanding old-time specimen. The Scott Williams label with the piece indicates the piece was acquired in February, 1960. As stated in the aurichalcite section, pp. 55-56 of the Mineralogical Record Mexico Special Issue II, Vol 34, No. 5, Sept.-Oct., 2003: "Aurichalcite in beautiful specimens is one of the signature minerals of the Ojuela Mine."; and "No aurichalcite specimens remotely comparable to these early ones (1950s and 60s) have been found in the Ojuela mine since the mid-1960s; it is a rare mineral on the market today."
10.0 x 8.0 x 3.7 cm. The Mina Ojuela has produced a new find of this beautiful and striking combination material. Beautiful, soft-to-the-touch, like felt, robin’s-egg blue aurichalcite needles richly line a vug atop a sculptural wedge of sturdy gossan matrix. A few, glassy, transparent calcite rhombs are scattered about and are included with aurichalcite.
10.3 x 6.4 x 3.4 cm. Sparkly, robin’s-egg blue aurichalcite lathes richly cover both sides of the sturdy gossan cabinet matrix on this fine and rare old-time specimen from a very uncommon Montana locale - the Cleopatra Mine in Beaverhead County. Comes with a faded, hand annotated label with a March 1944 date. Ex. Dennis Mullane Collection. I have never seen a specimen from this locality, to be honest. The Mullane collection incorporated an earlier collection of a newspaperman from Butte named Kessler, though, and he had a huge range of early 1900s minerals from obscure (today) western localities.
4.4 x 3.4 x 3.0 cm. “Rice-grain" smithsonite crystals on aurichalcite are amongst the most desirable combination specimens from the Kelly Mine. Gemmy, tiny, rice-grain smithsonite crystals are lavishly scattered on the gorgeous, powder-blue, banded, botryoidal aurichalcite lining the striking vug in gossan matrix. A very fine miniature from this locale. Ex. Jaime Bird Collection.
6.4 x 5.5 x 4.0 cm. Scintillating, gemmy, sea-green aurichalcite needles richly line a very scupltural vug in quartz-rich matrix on this striking and excellent specimen from a much les well-known mine in Chile - the Dos Adriana in Copiapo Province. These are some of the glassiest and brightest aurichalcite needles I have seen from any locality. Excellent material.
