Crystals of brilliantly lustrous, metallic hematite, to 2.4 cm in length, exhibit mirror bright faces and exceptionally unusual crystal form. Most hematite from this locale is rather thin and frilly. This is a robust, very mirror-like crystal of high calibre

Emanating from a spongy matrix of native silver, are numerous wires of silver to 1.2 cm in length.The wires and silver matrix all exhibit a variegated, dark gray patina.This is a cute, hefty miniature from Fresnillo.

A stunning cluster with exceptional lustre: This is a cute cluster of 3 bright crystals of acanthite, to 1.5 cm across.Two of the crystals appear to exhibit at least partial hopper growth, where the edges of the crystals grow faster than the faces, thus resulting in complex hollowed-out "crevasses" in some faces. Complete all around!

Two danburite crystals, to 8 cm in length, are the host for two, doubly-terminated, lustrous and translucent calcite crystals to 5 cm in length. The larger danburite crystal is glassy , with a super gemmy brightness and luster to it! The calcites present from the front, complete, though they have some portions missing or contacted on the backside. An excellent, rare combination piece.

This is a very cute, aesthetic combo specimen from Naica. Emplaced on a matrix of splendent galena, in cubes and modified cubes to 1 inch across, are glassy and gemmy, colorless fluoritecrystals. They are more gemmy and clear in person - always hard to photograph. Calcite drapes over the backside.

This cluster of tabular, lustrous and translucent, slightly manganoan-pink, rhombohedral calcites, to 4.5 cm in length, has formed a penetration twin. The specimen is SUPER fluorescent with a magnificent, bright orange color under UV. Absolutely pristine and quite unusual for its sharpness, this is a floater specimen

This is a fascinating, triangular shaped cluster of three large, slender, quartz crystals, to 7.5 cm in length. They are mostly opaque, milky prisms except at the terminations - which are glassy, gemmy,and colorless (very sparkly!). Although seemingly just cute and simple, the piece actually exhibits a lot of complexity when you start looking closely. Complete all around

A solid mass of lustrous, brassy-yellow crystals of pyrrhotite, to 2.5 cm in length, is surmounted by a single quartz crystal on one side. The other side is solid pyrrhotite. The quartz is an unusual association on the pyrrhotite, and is lustrous and translucent. The back side has several small spheres of what might be iron oxides attached. Overall a great example of this old classic find

A cluster of glassy and translucent, rich tan-colored danburite crystals, to 5 cm in length. The color is a bit unusual. They are aesthetically perched on a sliver of limonite matrix. Frankly, I can't rememember seeing another cluster with this rich tan color.The 3-dimensional splay of the crystals makes this piece very impactful, and a bit different than others

Scattered about in a jackstraw arrangement on a limonite matrix are several exceptionally glassy and gemmy, colorless crystals of gypsum to 7.7 cm in length. The two largest crystals are doubly terminated and both exhibit large phantoms at their centers that are beautiful, multi-colored gardens. A really nicer-than-most-such kind of specimen!

Nestled aesthetically in a vug of ocherous limonite, are calcite crystals heavily included by aurichalcite which gives them a superb, light teal-blue color. These are covered by a second generation of lustrous and translucent, colorless calcite, in crystals to 1.5 cm in length. In places on the limonite, are drusy clusters of lustrous and translucent, apple green conichalcite. Overall just a gorgeous piece with lots of subtle colors and color mixes. It has a small bit of damage, to a few peripheral crystals, but is otherwise in excellent condition. Unusual!

Bournonite is very rare at this locality. This is a solid , bright metallic mass of galena crystals to 2 cm across, with varying luster from satiny to splendent. Scattered on the galena are lustrous and translucent, light pastel-purple fluorite crystals, to 1.8 cm across. Small bournonite crystals, exhibiting the classic cog-wheel pattern so desirable, are present on some galena crystals, and reach 1 cm across. Additioinally,there are pods of splendent, brassy yellow, drusy, pyrite. A neat combo specimen, from this old classic locale !

Sharp, relatively large bournonite crystals for this locale are perched on lustrous black sphalerite crystals, associated with a druse of,sparkling, brassy yellow pyrite and minor drusy, white quartz. A few of the bournonite crystals are also doubly terminated. They are sharp and shwo the striations characteristic of this locale - once one of the world's great sources for this species

A superb, doubly terminated, tabular, crystal that measures 9.8 cm across, this is glassy and gemmy. The colorless gypsum is elegantly arranged on a matrix of drusy , sparkling calcite as if on a pedestal - you could not ask for more perfect placement. Despite its softness this piece is nearly pristine, with only the most trivial wear. The totally clear and limpid gypsum crystal is offset even more under fluorescence whre the calcite is imparted with a brown hue and the gypsum transmits the UV light. Simply wonderful!

Beautifully perched on a cluster of intergrown, lustrous, battleship-gray crystals of galena, are two amazing, almost invisible, glassy and gemmy, pastel-green fluorite crystals. The larger is 5.25 cm in length and both are absolutely stunning for their clarity and sharpness, with almost no edge wear (just a few very minor rubs). Ensconced within and goign through the galena is a single deeper green modified octohedral fluorite crystal , that imparts the color to what otherwise would be the totally colorless cubes . In fact, the galena is in the shape of a cast, having formed over something else yet. Under fluorescent light the fluorite exudes a rich purple color. Interestingly, a layer of calcite resides between the fluorite and galena and it glows a lovely light brown when under lfluorescence . This is an outstanding Naica fluorite of highly unusual aspect for its large, sharp, clean cubic form at a locale where most such crystals are heavily modified. Also, they are unusually large and glassy for this locality. It is a remarkable specimen, overall - very much mnore impressive in person
