3.7 x 3.0 x 2.9 cm. A nifty jackstraw cluster of gemmy, highly lustrous, colorless adamite crystals with the always desirable, purple tips from the famous 1981 find at Mina Ojuela, Mexico. The smaller crystals are beautifully gem-like, with their lavender, chisel-like terminations. Many of the crystals are doubly terminated. The scattered, attached gossan matrix is actually a nice compliment. Ex. Ed Swoboda Collection.
3.7 x 2.1 x 1.6 cm. It seems as if a matrix of calcite is overlain by radiating, acicular groups of colorless willemite; but actually the "calcite" is cobaltoan adamite which is very rare for Tsumeb. The cobalt-rich and decidedly pink adamite grades into a second generation of light green cuprian adamite, with a rare pyramidal-looking crystal form. Ex. Willy Israel Collection.
3.4 x 2.9 x 1.3 cm. There are numerous gemmy, deep green crystals of cuprian adamite, some doubly terminated to about 1 cm in length! The crystals have inclusions of Ferrilotharmeyerite which lends them color. Sprinkling them are sub-mm sized, but bright yellow beaverite. Ex. Willy Israel Collection.
5.7 x 4.1 x 2.4 cm. With superb luster and color on the 1-cm-long Willemite blades, they lay attractively on the green-blue druse of cuprian adamites for a sharp contrast. Ex. Willy Israel Collection.
7.9 x 7.4 x 3.3 cm. Attractively centered in the typical limonite matrix is a densely-packed cluster of whorls of translucent, yellow-green adamite. The patch of adamite measures 3 cm across.
5.0 x 3.1 x 2.2 cm. Glassy and lustrous, seafoam-green cuprian adamite crystals richly and attractively line a 2.2 cm wide vug lined with sparkly, botryoidal, green olivenite in sulfide matrix from Tsumeb. Ex. Rob Smith Collection.
2.4 x 1.8 x 1.7 cm. Lustrous and gemmy, emerald green, crystals of cuprian adamite, to .5 cm in length, are nestled in a vug of ocherous limonite. Tim Blackwood Collection.
2.2 x 1.7 x 1.3 cm. A curving group of lustrous and translucent crystals of emerald-green cuprian adamite, to 0.8 cm in length, is attached to a sliver of ocherous limonite matrix.
8.1 x 5.0 x 4.0 cm. Totally filling a vug in ochre-colored limonite, is a crust of sparkling, apple green cuprian adamite, in crystals reaching 2mm across.
2.9 x 1.8 x 1.5 cm. This is a fine, aesthetic cluster of glassy and translucent, deep emerald-green crystals of cuprian adamite, to 1.0 cm in length.
8.7 x 6.6 x 5.4 cm. A vug in limonite is filled with spherical clusters of sparkling, glassy, translucent, emerald green, cuprian adamite. The largest rosette is .8 cm across.
1.9 x 1.4 x 0.9 cm. A fine thumbnail cluster of lustrous, leaf-like blades of forest-green cuprian adamite from the famous and now-closed Tsumeb Mine.
12.3 x 7.0 x 3.0 cm. Bubbly, gemmy, rice-grain-shaped austinite crystals here abound on matrix covered also with small adamite crystals. The small white barytes add additional accent.
6.6 x 4.8 x 4.2 cm. Converging crystallization has formed several hemispherical sprays of luscious, super-bright, apple green adamite aesthetically perched as if climbing up a hill of contrasting limonite. The clusters average 1.8 cm across. Ex. Harold Urish Collection.
2.2 x 2 x 1.2 cm. A splendid fan of thick, intergrown Adamite crystals from the world’s premier locality for the species. Excellent color and glassy luster. Ex. Wendell E. Wilson Collection.
