This superb, rare combination specimen from Tsumeb has two major mimetite crystals arranged in a "vee" with gemmy blue tabular azurite and small wulfenite crystals. The mimetite crystals are perfect, striated and gemmy, measuring to 1.9 cm. From my personal collection. 9.4 x 4.5 x 2.5 cm.
Fine, translucent, lustrous twinned crystal of cerussite with a second, small bisecting twin. As with most of these crystals, it is partially incomplete and hollow as shown in the photos. Of superb quality and now uncommon on the market. 4.7 x 4.2 x 1.3 cm.
Exceptional miniature of bright red,prismatic,gem crystals of cinnabar with dolomite and quartz. Untwinned, prismatic crystals like this are quite rare from China. The cinnabar measures to 1.4 cm, and is lustrous, transparent to translucent, and well-terminated. As an added bonus, and unusual for the locality, there is well-crystallized colorless fluorite on both sides of the specimen. This is a truly aesthetic and superb specimen. 4.6 x 4.4 x 3.5 cm.
A somewhat crude, altered, tabular chalcocite crystal measuring 1.3 cm on matrix with several other smaller crystals. The chalcocite appears to be pseudo-hexagonal in form. 3.2 x 2.6 x 2.5 cm.
Balls of argentopyrite to 2 mm on proustite, both on a calcite matrix. The proustite is deep red in color and highly lustrous. The argentopyrite and proustite are in excellent contrast to the white calcite. Some minor damage to the proustite as shown in the photos. A superb and aesthetic example of this rare silver, iron sulphide. 6.1 x 4.3 x 3.4 cm.
Fine miniature of bournonite on siderite from this classic German iron mine. Georg Mine specimens are highly prized. The two main bournonite crystals measure to 1.3 cm across and are in excellent shape, with good luster and superb form. Ex. Harvard University, with labels as shown. From my personal collection. 3.5 x 3.4 x 1.4 cm.
Excellent crystal of this rare calcium oxalate. The translucent, lustrous crystal is included by smythite, a rare iron-nickel sulphide. The smythite is concentrated in the center of the crystal,which creates a great contrast with the lighter edges. There is some edge wear on the left side of the crystal; otherwise, it is fine. 3.4 x 2.8 x 2.2 cm.
Beautiful specimen of sprays of green primary malachite on a dark gossan matrix. The sprays measure to 1.9 cm. Malachite specimens of this quality from Betzdorf are uncommon on the market. From my personal collection; received in trade from Bill Larson. 8.2 x 6.7 x 4.1 cm.
From the type locality, this is an excellent cabinet specimen of light brown stolzite on quartz. The stolzite measures to about 4 mm and is fairly abundant. It shows typical, but weak, fluorescence. From my personal collection. Some broken quartz crystals as can be seen in the photos. 8.3 x 6.1 x 3.8 cm.
