5.9 x 4.4 x 3.2 cm. A stunning cluster of amethyst crystals from Las Vigas. The crystals have grown on a small shard of matrix, and are shooting out in every direction. The bit of paper that came with this says "Zweibel Feb. 1979", so the collector (Richard Hauck) evidently acquired this pretty piece from the Zweibels at that time. Ex. Richard Hauck Collection.
8.9 x 5.4 x 3.6 cm. Prehnites are classic from Paterson, but this one has the unusual distinction of having the prehnite clusters on a bed of lavender amethyst crystals. For reference, the large cluster measures 1.5 cm across. Ex. Richard Hauck Collection.
5.9 x 5.8 x 4.4 cm. A sizeable crystal of amethyst from the Georgia finds that shows why these are considered amongst the best American amethysts ever - the intense, glowing purple color that lights up like a Christmas bulb under good light. The crystal is complete, with a bit of natural contacting on the back side and the back of the top termination where it grew against matrix or another crystal. Ex. Richard Hauck Collection.
4.4 x 4.4 x 3.9 cm. An old-timer amethyst specimen of superb quality that came with a very old Wards label as well as another old label from a Philadelphia dealer. The specimen consists of 8 gemmy crystals with glassy luster, combining both smoky and amethystine hues.
11.9 x 5.4 x 6.9 cm. This is a big specimen of the famous "Blanchard Blue" fluorite from New Mexico, with its distinctive teal color. The crystals are isolated on the contrasting quartz rather than massed together, adding to the beauty of this piece. The largest crystal is a sizeable one that measures 2 cm along the edge.
5.2 x 4.8 x 2.2 cm. Ajoite is a rare mineral that is almost always seen as bright, blue-green inclusions in quartz crystals. You can see several occurrences of these inclusions in these two intergrown quartz crystals from Africa. Old material from the Richard Hauck collection.
10.4 x 8.9 x 5.4 cm. This is a fascinating pseudomorph specimen from a small batch that was in the Hauck Collection, from a find in the Atlas Mountains of Morocco. What you have is poker-chip crystals of baryte that have been pseudomorphed by super-sparkly quartz. This is from the same find that included pseudomorphs of quartz after fluorite.
4.3 x 3.3 x 2.9 cm. A fine galena spinel twin miniature of this style from Russia. The flattened, spinel twinned crystal stands up perfectly on a natural "base" of quartz, sphalerite, and even a brassy pyrite crystal.
17.8 x 14.4 x 8.8 cm. This is a very fine, large plate from an exciting find of around 3 years ago in China. The specimens combine transparent quartz crystals with forest-green crystal of epidote, here spread in a rich field on the matrix. These specimens could be unbalanced in various ways, but this one has a fine balance of quartz crystals scattered across the field of sharp epidotes.
17.9 x 16.4 x 9.6 cm. A large mound of transparent quartz crystals rising up strikingly from the matrix. Inside many of the crystals you can see acicular crystals of green actinolite, like little green needles. In a couple of places, the quartz is spiking through milky crystals of calcite.
14.5 x 12.4 x 10.2 cm. An incredible burst or "flower" of translucent calcite crystals, on a bed of purple amethyst. These fine, sharp scalenohedrons measure to over 3 cm.
13.1 x 8.5 x 8.1 cm. Nestled in a basaltic vug is a sparkly crystal druse of colorless quartz, upon which was deposited some incredibly bright and sparkly crystal clusters of the rare species Goosecreekite. Atop the Goosecreekite sits two pearlescent, translucent crystals of heulandite, the largest of which measures 4 cm across and is also doubly terminated.
12 x 10.2 x 7.2 cm. This is a significant specimen for the species, for the quite obvious reason that it has unusually large and well-developed crystals isolated on contrasting matrix.
Just a really pretty piece….unusual in the association, too. This small pocket came out a few months ago and to my knowledge is a first for the mine. The major quartz crystal slightly diverges at the top, or has a small contact, but I don’t think that divot is damage. In any case, it is an impressive and showy specimen. 9 x 8.8 x 4.8
BRILLIANTLY lustrous, elongated crystals of classic Arkansas quartz. 10.5 x 5.3 x 3.0 cm
