13.2 x 12.9 x 6.3 cm. This is a rare complete pocket from the old Bagdad locality with an amazing "scene" inside: tiny crystals of quartz have completely replaced the former aragonite crystals, but retaining the aragonite form, which you can clearly see in the spiky crystals. These pseudomorphs rise from a bed of quartz over a layer of massive green chrysocolla.
8.2 x 5.9 x 4.9 cm. A very pretty, coral-like specimen of stalactitic aragonite, which gets its color from the copper content.
11.9 x 9.2 x 4.8 cm. A very unusual Dal’negorsk manganoan calcite, in that the crystals are intergrown with straw-like crystals of white aragonite. The calcites have pretty pastel pink color and fine luster, and are in the form of gently curved rhombohedrons.
5.0 x 3.6 x 3.1 cm. A fine combination pseudomorph specimen from the Nikolaevskiy Mine at Dal’negorsk, Russia. Mirror-bright, jet-black ilvaite crystals richly cover all sides of the diverging cluster of green to brown siderite pseudomorphing very elongated aragonite needles. From finds in the 1990s. Ex. Ryan Bowling Collection.
7.1 x 5.8 x 5.5 cm. A coral-like "bloom" of aragonite from Wenshan, tinted a beautiful sky-blue hue from copper content.
10.4 x 7.9 x 5.8 cm. A coral-like bloom of aragonite from China, with a subtle pastel sky-blue color from copper content.
1.6 x 1.4 x 1.3 cm. Here is a fine thumbnail size specimen of the famous pseudomorphs of Copper after Aragonite from Corocoro. These floater specimens are well known from Bolivia for their great form and color.
4.5 x 3.9 x 2.9 cm. A superb example of the aragonites from this one-time find – not only beautiful, but an important new find of aragonite from anywhere, much less America. They have a unique look, with tiny crystals growing like teeth on an earlier generation of sharp, larger crystals
A beautiful doubly terminated, highly lustrous and translucent aragonite crystal with a girdle of smaller aragonite crystals from the TYPE LOCALITY in Aragon, Spain. Very trivial damage overall, which includes one broken smaller crystal and a couple of minute termination dings. These are barely noticeable. An excellent specimen for the locality. 4.1 x 2.6 x 2.3 cm
5.9 x 5.4 x 3.8 cm. A beautiful growth of stalactitic aragonite, with stunning sky-blue color from copper content. Note how the growth started out botryoidal, and then shifted to more branchlike forms as the stalactites grew.
17.8 x 13.7 x 6.0 cm. A very colorful and showy plate of bright lemon-yellow sulfur crystals, on matrix. Though there is some damage here and there, it is minor in context and does not detract much at all. The piece looks good from either side. Ex. Andrew Carnegie Collection.
20.2 x 9.3 x 7.9 cm. This is a beautiful specimen. The surreal blue color looks fake, painted. However, the color is actually due to copper inclusions. Note the obvious presence of a rare green mineral in small, sharp crystals: probably libethenite or brochantite. Both are found at the mine, and I have a sample sent out for analysis. Ex. Academy of Natural Sciences Philadelphia Collection.
11.4 x 6.4 x 4.7 cm. A superb example of the aragonites from this one-time find from several years ago – not only beautiful, but an important new find of aragonite from anywhere, much less America. They have a unique look, with tiny crystals growing like teeth on an earlier generation of sharp, larger crystals.
10.6 x 5.8 x 3.4 cm. These snowy growths of aragonite look like some sort of exotic flowers. They start off as rounded forms at the bottom then explode outwards into a burst of spiky crystals. Very soft and delicate, but nevertheless only one small contact on one "flower". Ex. Consie Prince Collection.
An extremely unusual and uncommon specimen of chalcedony replacing blocky aragonite crystals from the Big Bend Area of Texas! Ex Betty Llewellyn and Marty Zinn Collections. Betty was Martys mother. Old material, as the label and pedigree attests. 6.5 x 6.2 x 5.4 cm
