A vuggy, ocherous, limonite matrix is the host for this crust of very lustrous, aqua-green colored cuproadamite, which has bubbled into sphere-like masses where there is available room in the pockets. The piece overall is big and impressive, and shows well how these things form in crevasses in previously cracked rock matrix. The largest of the stalactite-like formations is 3.5 cm in length. The contrast in color between the intense green adamite and the ocherous brown matrix adds to the look of this as an "art object" and it really shows off in a display case.

This is a fascinating specimen of adamite and gypsum in vugs of ocherous limonite. The adamite, which fluoresces a beautiful emerald green, occurs in spheres, to 1.5 cm across. The gypsum crystals are acicular, highly unusual as is the association itself! The piece really "sparkles" overall with the contrasts. NOTE: Hand delivery must be arranged

Amethyst is VERY rare from Naica and large crystals literally almost unheard of - which makes this specimen a killer for the locale. Lustrous and translucent, light purple-colored amethyst crystals to 12.5 cm in length, form a floater bow-tie cluster! They have small bits of attached sphalerite in back, as the only contact. Although not gemmy, nor glassy like Guerrero or VeraCruz amethysts, this is a significant specimen in the size, habit, and locality representation departments. It is also very aesthetic, on its own merits.

Bladed, glassy and gemmy, colorless crystals, to 1.3 cm across, are aesthetically perched high on a matrix of drusy, pastel purple amethystine quartz . Quite lovely and elegant, this is like a little jewel!!! It is one of my favorite calcite thumbnails, period.

Perched aesthetically on matrix are six botryoids of sparkling, slightly translucent, scintillatating, orangy pink, rhodochrosite.The largest botryoid measures 1.7 cm across. A real gem of rhodo with an unusual color palate and an almost metallic sparkle to it!

A very geometrc specimen with several stout, twinned rhombohedrons of calcite, to 5.7 cm across. They are perched aesthetically, on a small amount of sphalerite. The calcite crystals are lustrous and translucent at the edges with a frosted colorless appearance. In fact the frosting is a later generation of gemmier calcite overgrowth on earlier formed calcite. The calcite glows a bright, vivid orange under a fluorescent light. Superb, and very classic in form for older finds here!

A classic combo piece from Mexico, these are seldom seen today! Enveloping a lustrous and translucent, stark white celestine crystal, measuring 8.75 cm in length, are purple fluorite crystals, to 2 cm across. The fluorites are lustrous and translucent and exhibit a light purple color. The piece actually is almost smothered with fluorite, complete except only for one broken crystal at upper-left as shown in the first photos. Nevertheless, that tilts out and away, and is not immediately notiecable although price was halved accordingly. It looks good form all sides, and up or down.

Unusual! This is a superbly crystallized and arranged specimen of manganoan adamite in which the adamite crystals show a gradation within them from adamite to manganoan-adamite. A concave matrix of ocherous limonite is supplanted by beautiful velvety spheres of black goethite, to 5 mm across. Emplaced on the goethite and a thin septa of limonite host rock are sprays of lustrous and translucent, bicolored, colorless to lavender-purpley, manganoan adamite. the pinwheel spreays reach nearly an inch, to 2.2 cm across. The adamite is colorless at the core and at the termination grades to a magnificent, lavender. All the adamite is lustrous and sparkling! The contrast in color and textures between the limonite, goethite, and the biclored adamite is just breathaking on this superb old specimen probably from the early 1980s adamite finds here.

This is a sparkling mass of intergrown, splendent, brilliantly metallic crystals of arsenopyrite, to 7 mm across. Small quartzes are mixed in , as well. Subtly different than modern Chinese material
