18.9 x 5.4 x 4.8 cm. This is a huge single compound crystal of Colorado smoky quartz, a doubly-terminated floater. The side faces, which have good luster, are really interesting in that this is a compound crystal with inter-penetrating forms. Ex. Richard Hauck and Earl Calvert Collections.
12.9 x 8.8 x 6.3 cm. A stately quartz specimen out of the Richard Hauck Collection, combining a whole range of classic Panasqueira minerals. Two tall quartz crystals, with chlorite in back, rise above a field of smaller crystals, decorated with translucent green fluorapatites, along with muscovite and siderite. To top it off, there are also crystals of ferberite and arsenopyrite to be seen. Old classic material from the 1960-s-1980s.
11.5 x 3.2 x 3.0 cm. An old Leadville piece, a specimen of "parallel" quartz which gets its name for obvious reasons of the pretty parallel growth of numbers of milky crystals. Ex. Richard Hauck Collection.
13.4 x 4.9 x 4.9 cm. Dozens of gemmy fluorapatites to 1.3 cm, on a field of micro siderite, cover one side of this large quartz crystal. A rich, old piece out of the Hauck Collection, from this classic locality.
8.4 x 7.9 x 3.5 cm. A striking, sculptural Guerrero amethyst specimen. Ex. Richardm Hauck, Eugene Sensel, and Bob Jones Collections.
10.0 x 7.1 x 6.2 cm. Epidote and quartz is a classic association from this old Colorado iron mine. Here, the quartz is dominant, in the form of slender, transparent crystals, to 5 cm. The epidote appears as opaque green crystals on the matrix and flecks on the quartz crystals. Ex. Richard Hauck Collection.
7.9 x 7.1 x 5.5 cm. Three “mushroom” tourmalines together, on a matrix of quartz crystals. They are almost always seen as singles, without matrix. The tourmalines are up to 3 cm across the top, slightly translucent, with deep pink to purple color. Found in the late 1990s, this was always a rare style.
10.8 x 4.4 x 3.8 cm. This is a complete and uncontacted, cactus-like stalactite covered with the most gemmy amethyst crystals you could ever imagine. They really are as pure as glassy gems, very unlike your typical amethyst from Brazil or other common localities. Ex. Richard Hauck Collection.
2.9 x 2.6 x 1.4 cm, 2.6 x 1.8 x 1.3 cm, 1.6 x 1.6 x 1.3 cm. Two thumbnails and one nice small miniature of beautiful pastel-pink color and sharp rose quartz crystals. Ex. Richard Hauck Collection.
12.2 x 11.3 x 10.0 cm. This is a very large cluster of slender quartz crystals of the most elegant tapered form, covered with salmon-colored crystals of rhodochrosite. The quartz crystals measure up to 7 cm in length. There are here and there sprinkled shiny little pyrites. Ex. Richard Hauck Collection.
4.4 x 4.4 x 2.5 cm. This is a truncated, doubly-terminated crystal with intense clarity and glass luster, penetrated by a second, smaller crystal of very unusual tabular form. Ex. Richard Hauck Collection.
7.9 x 3.9 x 3.4 cm. Big, fat spessartines to over one centimeter intermixed with smoky quartz crystals, pseudo-hexagonal "books" of muscovite and stark white feldspar, from Tongbei.
8.0 x 6.0 x 4.6 cm. A classic, old-time combination German specimen from the famous Clausthal area of the Harz Mountains. The very sculptural, 3-dimensional, mountain peak-like matrix of glassy, colorless quartz crystals is very richly covered with melted-look acanthite crystals. This specimen dates to the 1800s and comes from an old European collection, where everything dates to the 1800s.
7.6 x 2.9 x 2.7 cm. A bizarre, fine amethyst scepter from Brandberg, Namibia. This old-time specimen features a sharply hexagonal, opaque quartz core covered by a sharply terminated, glassy, translucent, light purple amethyst crystal. Weirdly, part of the amethyst crystal has been dissolved away. The amethyst is otherwise, pristine. Some very unusual pocket chemistry here.
5.8 x 3.8 x 2.0 cm. A highly lustrous and striated complete all-around and undamaged, jet-black ferberite crystal is highlighted by a 1.6 cm, upright, water-clear, flower petal-like, twinned calcite crystal. A colorless quartz crystal lies next to the calcite and the ferberite is lightly peppered with fluorite microcrystals.
