Dolomite and Pyrrhotite on Quartz - Morro Velho Gold Mine, Nova Lima, Minas Gerais,  Brazil

Dolomite crystals of this quality are rare from any location, and these translucent blades are heavily decorated by minute crystals of iridescent pyrrhotite (and some cubanite) to make them stand out. A very 3-dimensional specimen, overall! Bladed rosettes of lustrous, translucent dolomite to 4.5 cm across, are aesthetically emplaced on a colorless, gemmy, 7.0 cm across, quartz crystal. Usually one sees gemmy green siderite with minor dolomite but this is a superb PRIMARILY-dolomite specimen from one of the world’s deepest gold mines, and a fine source for good specimens as well (though miners bring them out at risk of losing their jobs!)

Epidote with Byssolite and Dolomite - Knappenwand, Pinzgau, Salzburg, Austria

This is a visually impressive epidote from the classic old locality, with unusually stoudt and thick crystals. They have lustre like glass! The terminations are remarkably 3-dimensional and stand out dramatically from the matrix which acts as a natural prop to the crystals for display purposes. You can see there is one hairline crack here, a repair. It it were not repaired, this would be a 25k piece for the size and beauty, and the rarity on matrix. So, while there is this problem, the price is definitely adjusted accordingly and you get a piece that LOOKS like it is far more valuable, and certainly has more visual impact period, than you could normally get in this price range.

I am told that this was one of the best pieces in the size range from the famous 1998 find here, which Horst Burkard brought out to Tucson of 1999. The crystals have superb lustre, oustanding form, and literally leap off the contrasting matrix at the viewer, for dramatic effect. The color contrast is what makes the piece in part, but also the 3-dimensionality of the crystals leaping out at you. They are complete around , with only a few trivial contacts on the sides and with all major crystals completely pristine. This is a showpiece, no doubt about it!

Cinnabar on Dolomite - Wanshan Mine, Guizhou Province, China

Until the early 1980’s, fine twinned cinnabar specimens from China were all but unheard of. In the last few years fine, untwined cinnabar specimens have come available. This magnificent specimen features a cluster of pristine, frosted, very lustrous, translucent, cherry red cinnabar crystals, to 2.0 cm across, aesthetically perched on ivory colored dolomite. These large untwinned crystals are actually LESS common than the twins we all wanted when they first came out, and often overlooked. This one is world class in color, size and aesthetics!

Outstanding Galena specimen from the St. Joseph Lead District, Vibernum Trend, Missouri. This modified 3.9 cm cube has excellent luster and form, and it sits on a matrix of Dolomite and Chalcopyrite. You could not design a specimen with better aesthetics - and it is BETTER IN PERSON!



4JD37 - Dolomite (twinned) on Quartz, Phengite - $ 95 SOLD
Brumado, Bahia, Brazil
miniature, 4.5 x 2.5 x 2.2 cm

Sorry, we have no images of this specimen at present.

What an interesting combination piece this is! A very nice quartz crystal (very minor ding on the tip) girdled with glassy, twinned modified dolomite crystals with light-blue phengite along the bottom. Three nice minerals for the price of one . BETTER IN PERSON!.

Fluorite on Dolomite - Shangbao Mine, Leiyang, Hunan Province, China

Gorgeous and complex coloration, combined with a total transparency, makes this Shangbao Mine piece stand out from its peers, many of which tend to be more simple mixes of color, or smaller crystals if this gemmy. Alternating highlighted edges of purple , and purple basal faces on the modified cuboctohedral crystals, contrast with the teal blue color of the fluorite core. The larger fluorite crystal atop is 4.5 cm across, almost two inches! The sidecar crystal is unusual in that it IS complete, but looks like half a crystal - as if a knife sliced it cleanly through during growth, and then the surface continued growing to form a new layer of skin over the core. So, you can look right into its middle. It probably formed as a constrained growth against a now-missing dolomite or feldspar crysatl, giving it that straight edge. The two crystals together are perched nicely atop the knoll of dolomite to display to their maximum extent, and complete all around. The piece has a color and transparency that make it glow, even with only minimal backlighting.

This is from a new pocket found at the end of 2008, and quietly trickled into Tucson in 2009. It is a select, cherrypicked piece featuring a zoned, multicolored 2.8-cm fluorite perched on beautiful, lustrous, dolomite crystals. The dolomites have a porcelain-like quality to them and the stark contrast in texture and geometry is appealing. The fluorite is pristine. The dolomite has one broken crystal in the front-middle-right side, which is trivial. The piece displays wonderfully but I must say has a sawed surface on the upper-right edge (which you do not see form the display face, anyhow). So, the piece is offered at a reduced price if i do not have to go and manually work down the sawed edge to hide the flat mark facing to the rear, ad would be moreexpensive otherwise. This may not bother some people, and if so you get a good deal for it. I know that quality specimens from this pocket were going for prices much higher than this, under the table and privately at Tucson. It will, in retrospect, turn out to be one of the more interesting fluorite combinations from China and is really a unique combination so far as I can see. NOTE: these exhibit the photographic property of metamerism. They change colors from halogen and professional bulbs (more blue) to indoor fluorescent lighting and even natural sunlight (more green). Examples from both are shown here. The change is startling if you do not expect it, and quite pronounced in the right lighting.

This is from a new pocket found at the end of 2008, and quietly trickled into Tucson in 2009. It is a select, cherrypicked piece featuring subtly phantomed, green-blue fluorite perched on beautiful, lustrous, dolomite crystals. The dolomites have a porcelain-like quality to them and the stark contrast in texture and geometry is appealing. The fluorite is pristine over the length of the display face and the crystals measure to 2 cm.

This is from a new pocket found at the end of 2008, and quietly trickled into Tucson in 2009. It is a select, cherrypicked piece featuring cuboctohedral purple crystals phantomed with deep purple cores. Only a handful of specimens in this pocket were purple! The fluorite is perched on beautiful, lustrous, dolomite crystals. The dolomites have a porcelain-like quality to them and the stark contrast in texture and geometry is appealing. The larger fluorite, 3.4 cm across, is pristine and the smaller one is nearly so (with only a small contact-induced spot on the far left edge of one corner). The dolomite on the display face has excellent lustre, and is complete except for only a few peripheral crystals. I know that quality specimens from this pocket were going for prices much higher than this, under the table and privately at Tucson. It will, in retrospect, turn out to be one of the more interesting fluorite combinations from China and is really a unique combination so far as I can see.

The dolomites have a porcelain-like quality to them and the stark contrast in texture and geometry is appealing. The fluorite is pristine over the length of the display face and the crystals measure to 4 cm. They are extremely 3-dimensional, really jumping off the plate. The dolomite plate is complete on the display face, sawed on the back to remove it cleanly from the host matrix. I know that quality specimens from this pocket were going for prices much higher than this, under the table and privately at Tucson. It will, in retrospect, turn out to be one of the more interesting fluorite combinations from China and is really a unique combination as well.
