Pale pink crystals of orthoclase measure to 1.9 cm on this old German classic. Orthoclase crystals of this color were often referred to as paradoxite. Minor quartz is also present. With older labels from Ward's Natural Science and Lidstrom's. 8.7 x 5.0 x 4.0 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.
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.
Excellent 19th century specimen of dull gray galena crystals to 5 mm accompanied by small siderite crystals and a few quartz crystals. Under magnification, some microcrystals of rutile are also visible. Ex. Dr. G. Garbari collection with label. 6.1 x 4.6 x 2.1 cm.
An excellent thumbnail of lustrous black ilvaite on quartz from Ernie Schlichter's thumbnail collection. The ilvaite measures almost 2.1 cm and is perfectly terminated. There are additional small ilvaite crystals in the quartz at the base of the specimen. 2.6 x 1.5 x 1.5 cm.
Aesthetic specimen of colorless calcite crystals to 2.6 cm on matrix with some microcrystals of smithsonite. Well balanced and undamaged. 5.4 x 3.8 x 3.3 cm.
Nice spray of chunky pink heulandite on a white mordenite matrix. The heulandite spray is zoned, with deeper color at the base. It measures 2.9 cm across and is undamaged. Very attractive in person. 5.4 x 5.0 x 4.2 cm.
A very attractive "rosette" of pale pink heulandite crystals is the main feature of this specimen. The rosette measures 3.2 cm across and is undamaged. Much more attractive in person - the lack of color contrast in the rosette made it difficult to photograph. 6.0 x 3.2 x 3.0 cm.
Superb thumbnail of babingtonite on prehnite from this classic New England locality. The babingtonite crystals measure to 1.2 cm and are sharp and lustrous for the species. The prehnite consists of two generations: a fine green, translucent ball, and a secondary growth of frosted, more prismatic crystals. The specimen is contacted on the reverse where it was originally attached to a rotted calcite matrix. 2.4 x 1.6 x 1.2 cm.
