This is very simply, a huge, well formed, rhomb of lustrous and translucent, calcite that has been RICHLY included by fibrous, richly colored blue aurichalcite. A minor contact on the back side is unimportant when compared to this crystal and its color, and its perfection on the display faces. Wow! For a single, impressive blue rhomb, this will definitely stand out upon any shelf. There is, I think, nothing quite like these in the mineral world.

A small miniature with huge impact, featuring two sharp, tabular rhombs of calcite to 3 cm across are heavily invested with a rich blue, fibrous aurichalcite.The crystals are lustrous and translucent except for one more transparent and colorless, gemmy corner. Large, elegant crystals for this find....and color! This is a stunning specimen, perhaps not for the lover of matrix pieces, fine nonetheless and worth it just for the unique, unearthly color.

Emplaced on limonite is a cluster of lustrous and translucent, rhombs of calcite, to 1.0 cm across. The crystals have been heavily included by fibrous, aurichalcite, resulting in a rich blue color. Nice, sharp thumbnail example with great color!

Aurichalcite in Calcite from Ojuela Mine, Mapimi, Durango, Mexico [db_pics/new09/aur29b.jpg]

This is a simple, stark matrix specimen of a single, equant, glassy and gemmy rhomb of calcite, measuring 1.5 cm across. It has been only very lightly included by fibrous aurichacite, resulting in a pastel blue color in shades and wisps internally. The crystal form and color contrast on the limonite are superb. Probably, this should be trimmed to be a much more significant thumbnail specimen of calcite from here, than left as a miniature.

A dusting of fibrous, blue aurichalcite covers its limonite matrix. Set in the center of the specimen is a lustrous and translucent, equant, calcite rhomb, measuring 1.1 cm across. The rhomb is colored a rich blue from fibrous inclusions of aurichalcite. STARK isolation and drama make this, if not a pricey piece, one of the most interesting visually as a collectible.

Pastel blue, fibrous aurichalcite covers its limonite matrix. Situated on top is a cluster of lustrous and translucent, equant, rhombs of calcite, to 1.25 cm . Differential inclusions of fibrous, aurichalcite have resulted in some rhombs having a rich, blue color, others ahving a pastel blue color. Unusual in this pocket!
