9.2 x 7.1 x 5.0 cm. Here is a large, complete, doubly-terminated amethyst crystal with fine luster. It is actually a floater, having formed small faces even on the underside where it formed on a knob of matrix, allowing the crystal to terminate 360 degrees around.
5.7 x 2.2 x 1.8 cm. A smoky quartz crystal covered all around with dozens of gemmy orange-red spessartine garnets.
7.5 x 4.2 x 4.1 cm. This is a fine single citrine crystal, complete all around, with bright golden color and glassy luster, as well as super transparency.
6.2 x 3.7 x 2.4 cm. This super-gemmy quartz crystal apparently broke off in the pocket, and then healed all over and formed faces to become a floater crystal. On one side, small crystals have formed and are partly embedded in the face, so that they show from the other side and add a pretty distinction to the crystal.
5.8 x 2.2 x 2.2 cm. Sparkly quartz crystals have grown on a floater crystal of ilvaite, which has been partially replaced and also coated with hematite.
15.1 x 11.4 x 5.3 cm. Razor-sharp, dark purple octahedra of fluorite, measuring to 2 cm on edge, embedded in stark white contrasting quartz. This is a very large and rich plate, with a couple of dozen crystals on it.
10.2 x 4.4 x 4.4 cm. A strange and very unusual old Zacatecas specimen, featuring a euhedral crystal of quartz, measuring 5 cm and tapering at its terminations, with a coating of malachite. There is also a patch of malachite at its base, where it meets the matrix. A cluster of etched calcite is on the side of the quartz crystal.
7.5 x 5.4 x 2.5 cm. A 7.0 cm tall quartz stalactite of sparkling, snow white, drusy quartz is the host for a few crystals of pearlescent barrerite, to 3.75 cm in length, a rare member of the zeolite family. Rarer still, this was from a one time discovery in Alaska. Ex. Martin Zinn Collection.
6.6 x 4.3 x 3.7 cm. Here is a fine Peruvian amethyst. It is pristine and complete all around, even crudely doubly-terminated on the bottom of all points. Ex. Martin Zinn Collection.
2.7 x 2.6 x 1.8 cm. This exceedingly rare species occurs as hackly, black crystals, to .5 cm across, associated with .5 cm in length, colorless quartz crystals. Both of these species are on earlier formed, blocky, dark gray crystals of tennantite, up to 1.0 cm across. This specimen has exceptional crystals, starkly perched on contrasting matrix because of the quartz sprays. Analyzed by Dr. Marcus Origlieri. Ex. Uli Bahmann Collection.
8.6 x 5.7 x 2.8 cm. Fine little red pyrargyrites ensconced with sharp galenas in contrasting quartz. Ex. Carl Rumpff and Stephan von Habsburg-Lothringen Collections.
4.8 x 3.4 x 2.7 cm. The thin layer of green pyromorphite coats large quartz crystals. Ex. Dr. Gary Hansen Collection.
6.4 x 4.6 x 2.6 cm. A fine cluster of dusted green pyromorphite draped over milky quartz crystals. An historic specimen from a fairly uncommon locality. Ex. Dr. Gary Hansen Collection.
10 x 5.7 x 4.5 cm. A very rare old locality specimen. It is very attractive, with a burst of broccoli-looking pyromorphite growing in the middle of clear quartzes. Ex. Dr. Gary Hansen Collection.
11.6 x 8 x 6.2 cm. The thin layer of green pyromorphite coats massive quartz and small quartz crystals on two sides of the specimen. Ex. Dr. Gary Hansen Collection.
