4.3 x 4.2 x 1.8 cm. A very attractive string of about nine intergrown crystals sitting atop a plate of very clear Quartz crystals. The Whiteites have a nice uniform tan color and very good luster. The crystals, interestingly, seem to always be in intergrown pairs about 1.3 cm in length. Ex. Martin Lewadny Collection.
8.7 x 5.6 x 2.0 cm. These crystals are very sharp for English bornite, and reach in size to 2.0 cm across. Perched on a translucent shard of crystallized, colorless quartz xls to 1.0 cm are several crystals of metallic gray, lustrous, pseudo-cubic crystals of bornite. Ex. Dr. Eric Asselborn Collection.
3.9 x 3.6 x 2.8 cm. This piece features beautiful dark azure crystals to 1 cm of scorodite from this very old locality. Ex. Rice Northwest Museum Collection.
8.7 x 6.7 x 6.3 cm. Found in June 1982, a classic combination piece for the locale. This piece features a repaired 2-inch smoky quartz on a plate of pastel blue amazonites. It is accented with nice albite in the spacing between the amazonites, for contrast. Ex. Rice Northwest Museum Collection.
5.0 x 4.6 x 3.0 cm. For sheer richness of color and coverage, this is a fine specimen, clearly old material from this important locality for crystallized turquoise. Ex. Rice Northwest Museum Collection.
15.3 x 8.0 x 5.5 cm. A beautiful lapidary object with a large several-inch rutile star embedded deep within the quartz, which has been polished to better reveal the internal inclusions. Ex. Rice Northwest Museum Collection.
12.0 x 4.8 x 3.3 cm. Bright green octahedra of fluorite isolated on a matrix of stark white contrasting quartz, from the Orange River.
7.9 x 5.9 x 4.3 cm. An old-time specimen of quartz from Colorado - two elegant prisms with a really unique look to them, in that their sides are frosted with glittering, sparkly microcrystals, that end abruptly at the start of the termination faces, which are smooth and lustrous. Ex. Richard Hauck Quartz Collection.
6.9 x 6.6 x 2.3 cm. A rare ARKANSAS faden quartz, a complete floater with only one small point of contact. The faden line is quite distinct, running right across the middle of the crystals. The tightly intergrown crystals have high luster and sharp terminations. Ex. Richard Hauck Quartz Collection.
6.5 x 3.9 x 3.3 cm. These are not the most beautiful quartz crystals on earth, admittedly - but the specimen is cool for having three Japan-Law twins in the space of just over 7 cm.
10.4 x 8.4 x 4.2 cm. There are gleaming crystals of arsenopyrite with beautiful saw-tooth edges. There is a very large mound of the rare sulfide stannite; sharp, gemmy quartz prisms; a covering of sparkly calcite; and even a couple of tiny, perfect scheelite crystals.
5.5 x 3.8 x 2.7 cm. An aesthetic Tsumeb specimen of a super-sharp, 3-sided, 2.5 x 2.3 cm tennantite crystal perched top milky quartz crystal matrix. The moderately lustrous tennantite is pristine and has textbook crystal form. Ex. Rob Smith Collection.
3.9 x 3.2 x 1.4 cm. A fine, 2.4 cm, translucent, tan ankerite crystal disc attached to a fine, L-shaped cluster of water-clear, doubly terminated solution quartz crystals from a rare find at the Jeffrey Quarry, near Little Rock, Arkansas. Ex. George Feist collection.
7.1 x 6.6 x 5.1 cm. A gemmy and lustrous, pristine, 4.0 cm, teal-blue, indicolite tourmaline nestled between three, very glassy, colorless quartz crystals from Pech, Afghanistan.
7.0 x 4.5 x 4.3 cm. A fine millerite specimen from the famed limestone quarries of Ollie, Iowa. A 6.0 x 2.0 cm sparkly, quartz-lined vug on snow-white limestone matrix is filled with very soft to the touch, hair-like millerite needles. Needles reach 2.0 cm on this excellent piece. Ex. George Feist Collection.
