7.0 x 5.2 x 5.1 cm. A classic, old-time and very showy combination specimen from the historic Elba Island of Italy. Extremely gemmy, orange spessartine garnets to 4 mm and lustrous smoky quartz crystals are aesthetically scattered on the orthoclase crystal matrix. The sharp, 4.0 x 2.2 cm, pearlescent, Carlsbad-twinned orthoclase crystal is superb. Ex. Richard Hauck Collection.
6.5 x 3.8 x 3.3 cm. The Veta Grande Claim, Dome Rock Mountains of La Paz County, Arizona has produced what are generally considered to be among the finest United States hematite specimens. This fine plate consists of mirror-bright hematite plates nicely scattered amongst a "forest" of water-clear quartz crystals. The 3.1 cm quartz “sentinel" is striking. The largest hematite crystal is 1.6 cm. Specimens of this quality were found in the 1970s. Ex. Richard Hauck Collection.
8.0 x 6.0 x 5.6 cm. A superb and classic Himalaya Mine combination specimen. A pristine, 6.3 cm, doubly terminated, watermelon-pink with gemmy, green termination is attached to the side of a near-flawless, translucent, complete all-around quartz crystal. Older material.
11.5 x 8.1 x 5.7 cm. A fine cabinet combination piece from the well-known, but abandoned Geigenberg Quarry of Austria. The quarry was mined for diabase. Two, fan-like clusters of lustrous, parallel-growth, olive-green clinozoisite blades are nestled in the center of a large vug and are surrounded and accented by milky quartz and light purple axinite, as distinct blades or in massive form. Ex. Rolf Wein Collection, an Alpine specialist and purchased in 1968.
3.3 x 2.6 x 1.2 cm. A superb goosecreekite miniature. Goosecreekite is a rare zeolite group species, worldwide and also from the Deccan Traps of India. An upright, thick, pearlescent goosecreekite blade is beautifully enveloped by a curved and branching quartz crystal stalactite. This is a very large goosecreekite crystal. This is a wonderful specimen of this rare species, probably from the Jalgaon or Nasik Districts of India. Ex. Carl Davis Collection.
8.6 x 6.7 x 3.2 cm. Brookite is a signature mineral species from the famous Magnet Cove deposit of Arkansas and this fine specimen is richly covered with splendent, metallic-gray, blocky brookite crystals to 1.3 cm on a sculptural, crystallized quartz matrix. Ex. Richard Hauck Collection.
7.1 x 3.4 x 3.1 cm. Sharply terminated smoky quartz crystals, such as this one, are rare, and are called the Tessin habit. This water-clear, 6-sided, ultra sharp spear-point is from Diamantina, Brazil. Ex Richard Hauck Collection. Older material.
4.5 x 3.5 x 3.1 cm. A rare tetrahedrite from this locality. Sharp crystals to 6mm in massive, hefty cluster upon quartz. Ex. Academy of Natural Sciences Philadelphia Collection.
A CHOICE miniature of Himalaya stilbite, with rich chocolatey color! Ex. Tim Sherburn Collection 3.6 x 3.2 x 2.7 cm
A really attractive large specimen featuring a classic Little 3 assemblage in decorative arrangement...the smoky in the middle is pristine save for one small contacted face (not damage), and is nicely accented by stark white albite and dozens of glittering little orange spessartines perched on every other species present (quartz, albite, muscovite blades) and even included within the smoky! 12.3 x 7.5 x 7.4 cm
An exquisite and sharp quartz crystal that is terminated ALL AROUND and shaped more like a sphene than a quartz. It has rich inclusions of jet black schorl crystals running inside. One side is glassy and the other dull, but overall it is quite transparent. This unusual specimen is the only such I have seen, and was included in the collection because the mine is really in the same pegmatite belt, though in the adjacent county. A purchase made by Tim Sherburn from the late Pomona club show in 1995. 5 x 4 x 0.6 cm
A remarkable miniature with two exceptionally gemmy tourmalines to 3 cm perched on the side of a smoky quartz crystal. They have brilliant lustre and an olive green color that is apparent in good lighting. This specimen was collected in attempts to find a "backdoor" into the Himalaya after the main adit collapsed, and before the mine was formally closed. 4.9 x 2.9 x 2.5 cm
2.9 x 1.8 x 1.7 cm. These are the typical very deep teal-blue, sharp and glossy crystals of lazulite that set the standard for the species at this locality in Canada. There is a pretty association here with gemmy crystals of siderite, and minor quartz.
10.4 x 8.8 x 7.1 cm. This is a really impressive and large crystal of baryte rising off a matrix of quartz and smaller barites, with a strange distinction: both the large crystal (7 cm) and the small ones are clear through the center and frosted on the bevels to either side of the clear stripe in the center. The large crystal even has two golden sections at the outer extremities.
8.4 x 6.2 x 3.4 cm. It is very rare to see pyromorphite from the Chinese finds on quartz. The stark white quartz causes the clusters of brilliant yellow-green pyromorphite to simply leap out at you. The crystals have an intense, sparkly luster.
