5.4 x 3.6 x 1.5 cm. A very large, unusually transparent, sparkling wheel of adamite crystals, complete 360 degrees around. This specimen sparkles and shines beautifully. There is just a bit of limonite matrix present, enough to add a nice accent, along with some small adamite sprays.
Three gorgeous and lustrous lime-green radial adamite sprays, one of which is projecting toward the viewer, from one of the premier adamite Mexican localities, Mapimi. A very aesthetic specimen. Ex Lloyd Tate Collection. This is old material. 3.6 x 1.8 x 1.3 cm
3.1 x 2.1 x 1.7 cm. This fine, complete all-around miniature features purple-tipped, lustrous and glassy, pastel-green to light brown, intergrown, arrowhead-shaped adamite crystals aesthetically set in a wedge of gossan matrix. From the famous 1981 find. Ex. George Elling Collection.
2.3 x 2.0 x 2.0 cm. A doubly terminated, gemmy and lustrous, bowtie-like cluster of yellow-greem adamite crystals. Ex. Allan Young Collection.
2.3 x 1.9 x 1.0 cm. This superb thumbnail has gemmy and lustrous cuprian adamite crystals covering massive cuprite matrix, from the Tsumeb Mine. Ex. Rob Smith Collection.
From the collection of adamite connoisseur Marty Zinn, a specimen with relatively large isolated bipyramidal crystals of adamite (rather than the usual clusters of microcrystals) to over one centimeter! Fine luster, color and translucency too. Adamites such as this are quite rare in comparison to the more familiar whorls and pinwheels. 5.3 x 5 x 2.3
4.8 x 3.1 x 0.9 cm. With only a hint of matrix at a few points on the back, this is basically a floater. This sinuous specimen of glassy and gemmy, light limey-yellow, adamite, is composed of convergent crystals which end up forming rounded groups connected very delicately one to the other. A very elegant and unusual new habit.
3.3 x 1.7 x 0.7 cm. The form of this adamite specimen is that of one egg on top of another. The adamite is glassy and gemmy and alight limey-yellow color. The crystals have grown together, exhibiting a rounded yet crystallized habit not seen before.
4.8 x 4.5 x 0.7 cm. From a minute amount of matrix, this adamite specimen grew into an exquisite, freeform piece of sculpture. The adamite is glassy and gemmy, with a light limey-yellow color. Just superb, and of a totally new habit form previous finds.
4.3 x 3.4 x 1.5 cm. A fairly significant specimen with robust, splaying crystals to over an inch in size. Growing in a divergent spray, this specimen of adamite is glassy and translucent, with a yellow-green color. The largest crystal is 3.5 cm in length. These large, fat adamite crystals are probably the rarest habit, historically, for green-yellow adamite from here.
5.5 x 3.7 x 2.5 cm. Aesthetically nestled in a limonite matrix, this adamite specimen has formed in a delightful, sinuous manner like a snake lying in a tree. The rounded crystal clusters are glassy, translucent and exhibit a lovely limey-green color. The spheres reach 1.5 cm across.
6.8 x 6.5 x 2.4 cm. Crystals, to 1.25 cm across, of glassy and gemmy, lime colored adamite are emplaced on a matrix of ocherous limonite.
9.4 x 5.8 x 0.9 cm. A thin, curving, crust of limonite is the host for a plate of intergrown crystals, to .5 cm in length, of glassy and gemmy, lime green colored adamite.
4.7 x 4.2 x 2.1 cm. Two rounded aggregates of translucent crystals of glassy and gemmy, lime green adamite. The "ball" widens to 3.0 cm across. One of the botryoids is a rosy-red color due to included limonite within the adamite.
9.0 x 5.3 x 3.6 cm. Vuggy limonite is the host for spheres of glassy and gemmy, translucent, lime colored adamite, to 1.2 cm across. The color and lustre are outrageous. This is a rich and colorful piece, of classically formed adamite in radial clusters.
