A colorless, glassy and gemmy crystal of celestine, measuring 6.2 cm in length , has become the matrix for a cluster of glassy and gemmy,purple crystals of fluorite, to 5 mm across. Superb quality in both species, makes these old classic combinations appealing today as well. Absolutely fascinating and quite striking!

Large octahedrons, to 6 cm across, of lustrous and translucent, light green fluorite are emplaced on lustrous, battleship gray crystals of galena, to 1.5 cm across. For added effect there are crystals of drusy, brassy yellow pyrite scattered about on the fluorites

Dramatic combination piece with colorless, lustrous and translucent, fluorite crystals to 2 cm across. They are intermixed with splendent, bright crystals of galena, some of which are spinel twins, to 2.5 cm across. Much better in person! This is a classic combination of species from Naica, but the presence of the spinel twinned galenas with the fluorite takes it up a level in interest

A glassy and gemmy, light-green crystal of fluorite, measuring 2.5 cm across, is nearly surrounded by rosettes of lustrous and translucent, white calcite to 8 mm in length. A drusy coating of brassy yellow pyrite also provides a halo for the fluorite crystal and creates an unusual combination piece

A superb small cabinet piece from the 2006 finds here, one which I sold at the time. The specimen is notable for its display qualities, and the rich contrasting association to the jet black sphalerite. Three crystals of lustrous and gemmy , nearly colorless fluorite to 3 cm across, are aesthetically perched high on a matrix of intergrown clusters of lustrous, metallic sphalerite (along with minor galena and chalcopyrite). The sphalerite is complexly crystallized form smaller crystals, and so throws off a lot of reflections in person, complementing the transparent fluorites above - through which the light just flies on through. The largest fluorite crystal exhibits a green color center although their "bodies" are colorless. Although not in the Heck collection of Mexican minerals as are most others in this update, this piece is from the Stoudt collection which I also recently acquired, and so fit well within the larger update. Out of hundreds and hundreds of pieces I handled (i bought entire lots direct at the mine, in this time), this was one of my favorites of the lot and i recommended it to one of my closest friends and collectors at the time, because of that reason. I stand by it today...such a quality has not been found since, and for my personal taste this remains one of the very finest of the find in its size range.

This specimen is composed of intergrown, lustrous and translucent fluorite crystals, to 4 cm across. The crystals exhibit a rich puple or grape color and clearly intricately stepped growth - for which this old locale is historically known and justifiably famous for. Interestingly, all the color is zoned at or near the surface, with the core being colorless. The intensity of that color is high for the mine (higher in person, in fact, than in the photos as they appear on my monitor), with few attaining such a dark hue as this. It is a fine and dramatic specimen from Muzquiz.

Superbly crystallized on a crust of splendent, metallic-silvery galena crystals, is a cluster of glassy and gemmy, pastel green fluorite crystals. they individually reach to 2.5 cm across, although of course as a cluster the width is much longer. The fluoreites have unusual rounded corners on many faces, with just a slight bevel suggestive of a modificaiton in growth. The fluorite crystals fluoresce a fantastic light lavender color. In person, in room lighting, the piece has a faint pastel green color to it. the lights for photography wash that out, a little bit. This is an outstanding combo specimen from Naica with sharp , symmetric fluorite crystals that just could not be perched more perfectly if you wished it. Such old piece are still the standard for "classic Naica style".

Stunning combination piece, that I would never have thought was Mexico myself, for its sharp gemmy phantoms. Wreathed by the sharp pink dogtooth-calcite crystals is an exquisite, glassy and gemmy, color-zoned fluorite crystal, measuring 2.5 cm across. The calcite fluoresces a rich orange and the fluorite a rich purple. Amazing combo!

Chalcopyrite, patinated green by oxidation, is the host for a spectacular, glassy and gemmy, octahedral crystal of fluorite, 2 cm in length, which is perched high on its matrix. The colorless fluorite crystal exhibits unusual growth on its crystal edges , and the faces appear to be slightly concave. In fact, the overall appearance of the fluorite is that of stepped growth, similar to the pyramids, but with some curves on closer inspection. The combination of fluorite on chalcopyrite is highly unusual from ANY locality
One of India’s sensations of recent years has been these spherical Fluorites, which are unparalleled for size and attractiveness. This particular specimen consists of three intergrown spheres (4 cm across!) that have a lovely medium honey color and are quite gemmy. Factor in the unusual association with amethystine quartz matrix, and you have an aesthetic and unusually displayable specimen.
How often do you ever find 15 cm Amethyst–lined Chalcedony vugs from India, let alone one with a stunning 2-inch (5-cm) hemispherical Fluorite sitting smack in the middle of it? Almost never, I would say. This Fluorite has two generations of quartz growth on it; one is a very fine druse that gives the crystal orb a very distinctive sparkle, and the other is a flat white growth that creates an appearance of clouds from space creeping over the globe of fluorite. VERY VERY NEAT EFFECT IN PERSON! It coulda been ugly, I admit, and its on the borderline of "weoird", but erred on the side of "cute" and not on the side of being too covered with the secondary quartz to call ugly. IN person, it sparkles like SUGAR. This is truly an incredible specimen, the likes of which I have not seen before from India
This terrific specimen consists of three Fluorite spheres (to 1.3 cm) and a 2-cm scalenohedron of Calcite, all perched on literally ropelike stalactites of translucent quartz crystals. Many of the quartz crystals actually comprise very attractive and visually delicate stalactites within the Chalcedony/basalt vug (the piece preserves some of the natural concavity in person, though it is sawed o nthe back to reduce the matrix weight). Given these ingredients, you could hardly put them together in a more aesthetic combination. A simple killer!
This is an unbelievable 6 cm (!!) spherical, honey-colored Fluorite with shiny, silky luster and a gemmy core. And...it is resting on Amethyst for amazing contrast! Very rarely will you find an Indian Fluorite this good, for both quality and size. It also happens to be perched in a well-balanced, colorful matrix. One of my favorites of all I have seen mined to date
This 2-inch (5 cm !) spherical Fluorite is a rarity – it has a true glassy luster which allows you to see that the crystal is actually gemmy virtually the entire way through. It is from a new locality in Jalgaon area, I am told, different than the previous Mahodari site. In fact, I’m not sure I have ever seen one of these Fluorites with such qualities, I would say otherwise...but in person the color and texture is subtly different, and the matrix of larger quartz points really stands out uniquely compared to the more flat matrix quartz of the Mahodari material we have seen before. The back and sides have been sheared off with diagonal sawcuts, you cannot see form the front, to reduce the mass. This material seems to come out of a deposit with much thicker quartz rinds, and also much larger quartz crystals, than the other material. It is thus necessary to reduce the specimen considerably from the raw state to get it to a size we can lug around. Considering the size, luster, gemminess, and good light-honey color, this is clearly a superb specimen.
A superb example from the recent find at Clay Center of glassy, amber-colored fluorites in association with milky crystals of celestite. Clay Center has long been known as a fluorite specimen locality; the crystals can range from transparent such as this, to a rather murky brown. This largish crystal has just a couple of tiny spots of edge-wear, so it in wonderful condition – and as you can see, the aesthetics are great too.
