3.6 x 3.6 x 1.2 cm. Two gemmy and lustrous, reddish-orange wulfenite crystals set on a plate of bedded, gray calcite from the famous 2003 find at the Red Cloud Mine. The large, isolated crystal is 1.2 cm. Calcite is an uncommon matrix material from the Red Cloud Mine.
4.6 x 2.5 x 0.6 cm. A fine silver "feather" of isolated, very elongated, spinel-twinned silver crystals accented by calcite and a bit of matrix from the famous finds at the New Nevada Mine at Batopilas, Mexico in the early 1980s. The silver crystals have a very nice, iridescent patina.
4.7 x 3.3 x 2.8 cm. These Elk Creek barytes are American classics. Here is a gemmy crystal of 3.5 cm, sharp as a razor, jutting off the matrix. The faces are complete and razor-sharp.
18.8 x 12.9 x 9.4 cm. This fine Bisbee calcite specimen came out of the Holbrook Shaft.
11.9 x 10.4 x 5.3 cm. The matrix here is covered on all sides with gemmy, golden crystals of fluorite. You can also see some colorless, transparent calcite twins in a patch to one side of the specimen.
10.9 x 7.5 x 7.3 cm. A large, fine calcite crystal jutting up from a sparing matrix covered with little chalcopyrites and some galena, out of the Feist Collection. It has a perfect pyramidal termination, the typical light yellow-golden translucency, and sharp faces all around.
22.9 x 13.8 x 14.8 cm. A beautifully trimmed-out side of a large pocket gleaming with crystals - gemmy, light green apophyllites; pearly, slightly peach-colored stilbites; and even some very large calcite crystals, once of them very large - quite unusual to see, in fact, with these combination pieces.
17.6 x 15.4 x 12.9 cm. A transparent, light golden calcite crystal sharp as a razor and measuring over 5 cm along the edge is beautifully centered in a pocket lined with micro apophyllites. The calcite is sharply twinned, as you can see from the many planes and angles showing, and is also nice for its translucence. A little "bridge" extends from the calcite, connected with a bit of peach-colored stilbite.
23.9 x 16.2 x 7.6 cm. These glassy calcites came out about 3 years ago in China, and stopped coming out maybe a year afterwards. They are very distinctive in appearance, with razor-sharp pyramidal termination, super luster, and internal phantoms from an initial generation of growth. They are fat and stubby, measuring up to over 3 cm across the terminations.
6.2 x 3.8 x 3.8 cm. A razor-sharp 3 cm rhomb that sits perfectly on three smaller Calcite rhombs and a sparkly matrix with drusy Quartz and a dusting of Duftite. The larger Calcite has superb luster and is gemmy to translucent. Ex. Martin Lewadny Collection.
5.9 x 4 x 3.2 cm. A sparkling, beautiful specimen with a drusy Quartz layer that coats the sharp Calcite. The edges have a very distinct translucent appearance which adds even more to the aesthetics of this piece. Classic Naica material from the mid to late 1980s.
9.9 x 8.9 x 6.3 cm. A big, pretty specimen of Gila County malachite on chrysocolla, out of the collection of Dave Stoudt. The malachite appears as rich forest-green balls, and you can see the layer of light blue-green chrysocolla peeking through. Ex. Stoudt Collection.
7.5 x 5.9 x 4.9 cm. This is a fine Berg Aukas descloizite, with large, beautifully-articulated crystals, and in this case, an unusual bonus: a sprinkling of calcite crystals. Ex. Willy Israel Collection.
5.3 x 5.2 x 2.8 cm. Bright yellow orpiment intergrown with, and in some places included inside, sharp prisms of calcite -- from Shimen, a noted locality for realgars and closely-related orpiment.
12.3 x 8.0 x 5.8 cm. This is a large plate of Mexican amethyst, the crystals having milky bottoms and purple terminations, with platy calcites sprinkled amongst them. Ex. Richard Hauck Collection.
