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. 6.1 x 4.3 x 3.4 cm.
From my personal collection, this is a terrific German mimetite reminiscent of "campylite" from Caldbeck Fells. The crystals are a brilliant yellow-orange and measure to 4 mm. This find was described in the April 2000 Lapis magazine. 9.7 x 9.6 x 7.8 cm.
From my personal collection, amber-colored stilbite bowties to 1 cm from an unusual German locality. The stilbite formed within vesicles in a basaltic matrix, clearly visible on the specimen. 4.7 x 4.4 x 4.4 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. 8.3 x 6.1 x 3.8 cm.
From my personal collection, this is a fine specimen of lustrous groutite crystals to 3 mm inside a manganese oxide and limonite nodule. The groutite crystals from the Emilie Mine are some of the finest in the world. 5.7 x 5.7 x 4.6 cm.
From my personal collection, this is an excellent specimen of slightly corroded pyrite crystals on scalenohedral calcite from Schlema. The pyrite crystals measure to 2.2 cm and the calcite measures to about 5 mm. 7.3 x 5.9 x 3.6 cm.
From my personal collection, an excellent specimen of arborescent native silver on a pinkish baryte matrix from a classic Black Forest locality. This specimen dates back at least 90 years; the mine closed in 1939. Undamaged and superb. 6.0 x 5.2 x 2.6 cm.
Fine specimen of the rare zeolite gonnardite. The gonnardite is in small creamy-white clusters on microcrystalline gismondine or phillipsite. As can be seen in the close-up photo, the specimen is in superb shape. From my personal collection. 6.6 x 5.5 x 3.0 cm.
Sprays of malachite crystals to 5 mm in length lie flat on a massive chalcopyrite matrix. Good specimen from a somewhat rare locality, with two old labels. From my personal collection. 6.2 x 5.7 x 3.0 cm.
