9.7 x 8.2 x 4.6 cm. A gorgeous and totally stereotypic cluster for "ram’s-horn" selenite. This quality is seen out of Morocco occasionally, and a few other places, but I had not yet seen any of this habit in quality, from China. It was bound to be there, but seems to not be common as opposed to more typical crystallized selenite. These ram’s horns are glistening, like wet sugar, and totally pristine and undamaged.
6.3 x 4.7 x 3.5 cm. In the mid-1990s beautiful combination specimens of atacamite in gypsum were available from the Lily Mine. This is a fine example where the dark green atacamite is included in transparent, colorless crystals of gypsum, which measure up to 2.5 cm in length. Ex. Martin Zinn Collection.
4.6 x 2.8 x 2.8 cm. A rare and fine twinned gypsum (variety selenite) crystal from the Rosh Pinah Mine of Namibia. The blocky, V-twinned crystal is super sharp and water-clear and has a beautiful amber tint. The smaller crystal in the "V" is a beautiful accent. This crystal is complete-all-around and pristine. It comes from the one-time, 1987 find at the mine.
13.5 x 7.8 x 4.0 cm. A beautiful, butterfly-twin calcite crystal on a cabinet plate from the small, one-time find in the early 2000s from Ametista do Sul, Brazil. The 3.1 cm, gem-like, calcite crystal beautifully lies on 3-dimensional basalt matrix covered with light amber calcite rhombs and strikingly studded with sparkly, water-clear selenite needles and crystals to 2.7 cm. These have not been available since the find came out about 7 years ago.
10 x 8 x 4 cm. A superb old specimen from the Mining Academy in Freiberg, circa late 1800s, this is a significant German galena specimen. It has large galena crystals and has a bizarre association with little bowtie clusters of selenite. It also has association with sphalerite and quartz.
7.0 x 6.6 x 4.0 cm. A rare combination specimen of sharp, white dolomite rhombs enclosed in a transparent gypsum cleavage from the Penfield Quarry of New York. The interior looks like a dolomite crystal garden in a lucite box. The Penfield Quarry is a road metal quarry in the Lockport Dolomite. Ex. Mullane Collection.
A 3.5-cm, doubly-terminated, water-clear crystal of selenite included by fine needles of bright atacamite, perched dramatically at the top of the matrix. Note that these have gotten much harder to come by! 5.4 x 4.1 x 1.0 cm
7.5 x 6.3 x 4.8 cm. A fine plate dominated by a gem, 4.7 cm, fishtail-twinned, intense orange gypsum crystal on a bed of smaller, un-twinned crystals. The large gypsum is pristine. This is one of the very best Peruvian gypsums we have seen, in particular because it preserves the halite association (many of them get dissolved away in situ). The large crystal is very gemmy and colorful. Ex. Ed David Collection.
Bright, golden-yellow, gemmy twins of gypsum to over 3 cm, piled up into a tower on a matrix of translucent fluorite. These are not the color of the more familiar twins on the "balls" from Canada, but a much more intense and pretty color. 9.6 x 8.2 x 6.6 cm
4.7 x 3.4 x 2.6 cm. Some of the best, if not the best, selenite crystals have come from the Naica District of Mexico. This visually striking and sculptural, water-clear, gem-like crystal has riveting side striations and gorgeous, twin-like striations on the sloped face. And the crystal is doubly terminated. The bit of attached gossan matrix is a nice accent. Complete-all-around and nearly pristine.
8.5 x 5.0 x 1.7 cm. An old-time, rare and aesthetic pseudomorph from Ray, Arizona and the Ed Swoboda Collection. Malachite has replaced a very elegant spray of blocky, tabular gypsum crystals. The central "tower" and the two, leaning "towers" to the left are striking. Iron oxides partially coat the malachite and give a very distinctive look to this superb and rare pseudomorph. Old material. The major, upright crystals are pristine.
10.7 x 4.0 x 1.2 cm. A fine and rich specimen of bright, micro-dendritic copper in a sawed, transparent cabinet gypsum cleavage from the Mission Mine of Arizona. Old material. Ex. Mullane Collection.
Spectacular in person, this is a large plate of sparkling starbursts of gemmy selenite crystals, from Australia. The overall form is wonderful, and the face is quite 3-dimensional, with the starburst piled up in places to form hillocks. Wonderful! 15 x 11.5 x 3.5 cm
A glass-clear tabular crystal of gypsum with bright green needle-like crystals of atacamite included inside. 4 x 3.2 x 2 cm
A DAZZLING plate of gemmy gypsum twins of an intense orange (not the more familiar pale color of the gypsum twin “balls” from Winnipeg). In terms of bang for your buck, it is hard to beat these for beautiful crystal quality and sheer pizzazz. 10.5 x 7 x 4.2 cm
