Isolated, fat crystals of adamite are actually very uncommon, even here at this once-productive locality. Pieces like this, with a radial grouping of such crystals - never were common. The piece features over a dozen such robust crystals to nearly 2 cm tall, curling up and over the top of a knoll of gossan matrix. It is aesthetic, sparkly, and colorful. More than that, it is a rare and beautiful style that sticks out amongst more common crystal formations for adamite at this important locality. It is old, certainly pre-1980s, we think.

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 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

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.
