WMISC-10/49 - Andradite (var. demantoide)

Las Vigas (Veracruz, Mexico)

Crystals of translucent to transparent apple-green demantoide to 4 mm. across on matrix associated with white laumontite. The largest crystals are mainly rhombododecahedral while the smallest are trapezohedral (dull translucent faces) with small rhombododecahedral faces (shiny and showing the gemmy interior). There is a first generation of small lustrous light tan colored andradite crystals to 1 mm. across. Just a tiny nick on one of the main crystals as only damage. Old specimen of a mineral rarely seen from this classic locality world-famous for amethyst. Nice to see under magnification.

WMISC-10/51 - Andradite (var. demantoide)

Las Vigas (Veracruz, Mexico)

Complex crystals of translucent to transparent apple-green demantoide to 2 mm. across on matrix associated with white laumontite. Most faces are dull and translucent while the small rhombododecahedral faces are shiny and show the gemmy interior. Quite clean of damage with minor broken crystals here and there. Old specimen of a mineral rarely seen from this classic locality world-famous for amethyst. Nice to see under magnification.

WMISC-10/52 - Andradite (var. demantoide)

Las Vigas (Veracruz, Mexico)

Large piece of matrix with all its surfaces coated by tiny shiny olive-green translucent crystals of andradite and some white laumontite. There is a central vug with complex translucent dark apple-green demantoide crystals to about 7 mm. across. Quite clean of damage. Old specimen of a mineral rarely seen from this classic locality world-famous for amethyst. Nice to see under magnification.

WMISC-10/53 - Andradite (var. demantoide)

Las Vigas (Veracruz, Mexico)

Matrix coated on the top surface by small shiny opaque complex crystals of whitish green andradite to about 4 mm. across (most around 2 mm.) with some crystals of apple-green translucent demantoide to about 5 mm. across. Some small rhombododecahedral faces are shiny and show the gemmy interior. Very nice contrast between both groups of crystals as seen in the pictures. Quite clean of damage. Old specimen of a mineral rarely seen from this classic locality world-famous for amethyst. Nice to see under magnification.

WMISC-10/54 - Andradite (var. demantoide)

Las Vigas (Veracruz, Mexico)

Large piece of matrix with most of its surfaces coated by tiny light tan colored crystals of andradite and some white laumontite. There is a central vug with complex translucent dark apple-green demantoide crystals to about 5 mm. across. Here and there small (to 2 mm.) gemmy crystals mostly with rombododecahedral faces rest on the matrix. Quite clean of damage. Old specimen of a mineral rarely seen from this classic locality world-famous for amethyst. Nice to see under magnification.

WMISC-10/63 - Descloizite after wulfenite

Erupción/Ahumada Mine, Los Lamentos District (Chihuahua, Mexico)

Cluster of previous crystals of wulfenite up to about 2 cm. on edge and 0.7 cm. thick now completely coated/replaced by small 1 mm. lustrous brownish crystals of descloizite. On the edge of the specimen some crystals are broken and void with the open space filled with tiny lustrous transparent brown crystals of vanadinite to 2 mm. long. This vanadinite seems to grow by dissolving the previous wulfenite as can be seen in one area with some remnants of etched orange wulfenite to 1 cm. across in direct association with the vanadinite. There is a last partial coating of tiny greyish crystals of calcite on some faces of the large crystals. Undamaged and a quite interesting example of pseudomorph/epimorph. I just prefer not to imagine how this specimen would be with the original wulfenite before the process of replacement took place.

WMISC-S/N-1 - Calcite and hematite

Santa Eulalia (Chihuahua, Mexico)

Hematitic matrix covered with hundreds of small lustrous hematite-included calcite crystals to 3 mm. Two undamaged colorless calcite twins to 1.3 cm. stand nicely as seen in the pictures.

WMISC-09/14 - Molibdenite

Inca de Oro (Copiapó, Chile)

Flakes and metallic grey hexagonal crystals of molibdenite to about 1.2 cm. across in matrix. A nice representative of a relatively common species but difficult to find in good well defined crystals.
