Danburite from Charcas, San Luis Potosi, Mexico [db_pics/heck/HECK034c.jpg]

Rising up from its sugary, calcite matrix, are two magnificent, glassy and gemmy, crystals of danburite to 8.5 cm in length. Although the crystals are colorless, they do exhibit the faintest hint of pink in fluorescent lighting. The danburites from Charcas are arguably the world's best of species for quality and gemminess both. The crystals are pristine save for a narrow conchoidal fracture on the back side of the termination, on the smaller crystal. The slightly irregular termination atop the larger crystal looks jagged at first glance but quite clearly in person is not damage, but rather some interesting little growth patterns on that edge of the termination. this would be from find sof the early 1980s. It is a superb, 3-dimensional specimen that has a lot more "bling" than most of these. If not for the damage at the back of the lesser termination, it would cost far more (like quadruple the price). Even so, it displays well from front and is a beautiful piece in the case, of a quality so hard to obtain for this species. Today's modern finds of the material here simply do not have the glassiness and lustre.

Perched aesthetically, high on a matrix of drusy calcite, are several glassy and gemmy, colorless, calcite crystals to 2.6 cm in length. The longest crystal is also doubly terminated (though with very slight edge wear on one tip, which can be removed with acid if desired). The calcite crystals are absolutely limpid and the form is highly unusual

Aesthetically perched on a sharp "spear" of snow-white celestite are cubes of glassy and gemmy, pastel purple, cubes of fluorite, to 1.1 cm across. This piece is exceptional for several reasons: the stark sharpness of the chisel-shaped celestite; the exceptionally gemmy cubes of fluorite; and the overall aesthetics. As well ,most of these were big and ugly - to find an aesthetic miniature is actually more difficult than to own a larger specimen

A core of intergrown, glassy and gemmy, nearly colorless fluorite crystals (with a faint straw color), to 1.6 cm across is almost covered on both sides by rosettes of lustrous, light-brown calcite crystals, to 2 cm in length. Unusual in its aspect, and complete all around

Bournonite with Fluorite and Galena from Naica, Chihuahua, Mexico [db_pics/heck/HECK026d.jpg]

RARE for the locale, this vuggy matrix of lustrous, battleship gray galena hosts striated, darker gray crystals of bournonite, to 8 mm across. I cannot recall seeing but 2 or 3 Naica bournonites before. The matrix is also filled with glassy and gemmy, colorless fluorite cubes to 3.2 cm across - thus proving the piece is from Naica by its style or I would have thought the bournonite was from elsewhere. The fluorite exhibits a faint green fluorescence. Aesthetic , and displaying the rare association, this is a combo piece that is worth more than the sum of its parts!

Two, sharp and unusually isolated, pastel green fluorite crystals to 3.75 cm across are aestheically perced high on a galena and pyrite matrix. The fluorites fluoresce a medium lavender color. Interestingly, the pyrites are weird bladed habits…and surely they are pseudomorph replacements of earlier pyrrhotite but now with the pyrite composition, and sparkle and coloration to boot. This is a flashy piece in person, with sparkle off of all three species present.

A matrix of splendent, brassy yellow, pyrite crystals , to 6 mm across, is the host for bright crystals of galena, to 1.5 cm across. For added effect, there is a rosette of lustrous, creamy white calcite, measuring 1.5 cm across.

Scattered on the sharp white quartz points here, radiating out, are lustrous and translucent, honey colored, fishtail twins of gypsum, to 3 cm in length. A few of the gypsum crystals are also doubly terminated. The quartz fluoresces a rich purple color. Lovely combo piece!

A dramatic and sculptural specimen ! Here, a second generation druse of sparkling, snow white, calcite has grown on a cast of what was once robust calcite rhombohedrons (now hollowed out and cast over by 2 generations of later calcite. The calcite rhombs reached 7.5 cm in length. The calcite fluoresces an intense, deep orangey red color (due to manganese). This is a really dramatic piece, for form and stark simplicity of color/form

Citrine has always been rare from this classic locality, and highly desired by the collectors. Two crystals of lustrous and translucent, orangey-layered quartz, to 6.5 cm, in length have been nearly enveloped by a secondary, sugary druse of sparkling tan colored citrine (you can see the layering from below). Scintillating and bright, this piece just sparkles!

A drusy crust of gypsum, tan on the outside and white in the center, is the natural pedestal for two glassy and gemmy, colorless spearheads of gypsum, to 5.5 cm in length. The larger crystal is also doubly terminated. The aesthetics of the piece are really outstanding, and it is not "just another gypsum " !

A cute miniature from mid-1970s finds here! The bladed crystals of white barite and yellow wulfenite compliment each other beautifully. The lustrous, white barite to 8 mm across nearly surrounds the window pane blades of lustrous and translucent, yellow wulfenite, to 2.5 cm across. Additionally, at the base of the wulfenite crystals are small orengey spheres of mimetite, to 3 mm across. Minor edge wear on one of the wulfenite crystals ( to be expected in such things), but otherwise complete all around

This matrix fluorite specimen exhibits dramatic stepped growth and intense purple color. The composite crystals , to 4 cm across on an edge, are lustrous and translucent - and possess the most spectacular rich grape color we have seen in Mexican fluorite. There is some very minor damage to the edges.

This specimen features unusually flattened, lustrous and translucent calcites perched on colorless quartz crystals, to 1 cm in length. Associated with the quartz are splendent, brassy yellow crystals of chalcopyrite, to 1 cm across. The disk shaped crystals of lustrous and translucent, white calcite crystals, to 3.25 cm across, are then perched on both the quartz and chalcopyrite. Neat combo specimen!
