This rare mineral, named after David London, professor of geology and geophysics at the University of Oklahoma, is the cesium-dominant analogue of rhodizite. All major finds worldwide occured in Madagascar where also this fine specimen origins. The single lemon-yellow translucent crystal with a greenish core has a typical and perfectly developed deltoid-dodecahedral shape and is free of any damage. The size is rather dramatic and exceptional as so few pieces of this mineral have been found so far. A major example of a very rare mineral out of a unique 2015 find.

This small marvel is a very well balanced association of two parallel pink and green tourmaline crystals on smoky quartz. It is a complete floater and free of any considerable damage.

3-dimensionally arranged acicular rutile needles on tabular hematite, characteristic for the famous locale of Novo Horizonte. The straw-yellow rutile is in surprisingly good condition though, as is inevitable on a fragile piece like this, not perfect. An appealing piece of metallic luster and stark contrast.

The quality of the flattened crystalized gold is totally astonishing as is typical for the locale. Sharp crystals of marvelous brigth luster and superg golden color are 3-dimensionally grown on a well proportioned white quartz matrix.

SO111 - Datolite on Quartz - Sold
Bor Pit, Dal'negorsk, Kavalerovo Mining District, Primorskiy Kray, Russia
Size: 18.3 x 12.7 x 7.7 cm
Watch Video
 
 
 

The shape of this datolite/quartz combination is extremely rare and in an untamed and chaotic way very aesthetic! A rather large pastel green and lustrous datolite crystal, 5.2 cm across, sits amid a "V" shaped array of unusual quartz crystals. The weird quartz shape that gives the impression of shifted layers results from intergrown calcite that dissolved later on. The whole piece is in exceptional condition and shows a number of smaller datolite crystals on all sides. Dal'negorsk is known as the worlds best locality for specimen-quality datolite which is clear when you see this fantastic and utterly unique specimen!


RK424 - Chalcopyrite on Barite - Sold
Shaft 371, Schlema-Hartenstein District, Erzgebirge, Saxony, Germany
Size: 8.1 x 6.3 x 2.8 cm
Watch Video
 
 
 

Sparkling colors on a snow-white barite background are totally intriguing and bizarrely attractive in person! Unlike normal chalcopyrite with its uniform golden sheen, this specimen is a rich play of colors, ranging over all kinds of tempering colors from blue and green to purple and loud pink. The white background provides the dramatic contrast for all those colors and makes this a just wonderful piece. The background is largely crystallized too with only some contacts and peripheral breaks. A unusual piece of sparkling colors and a manifold of tetrahedral crystals up to around 1 cm in diameter.

This is truly an exceptional piece of unique, etched shape! Our video reveals the 3-dimensional character of this amazing quartz. The upper part shows a deep gash as if someone wanted to cut away a major piece. Very fragile looking and astounding in a way. The quartz is completely clear with a mostly silky surface - yet in some parts a look to the interior is granted through glassy surface patches. A floater without damage that is full of pretty details and impressive as a whole!

Quality and color of this incredible titanite crystal are absolutely matchless indeed and much better in person! The slender twin-crystal has a brilliant gemmy core of just amazing color, apple green to dark emerald green, appealingly gleaming in the light. The crystal shows some edgewear but the mindblowing quality more than makes up for that. I have in fact hardly ever seen a crystal like that so go on and have a look on our video, where color and gemminess are displayed much better!

Like a shiny white tower against a dark horizon. A lovely crystallized elongated quartz cluster is embedded in a massy metallic sphalerite crystal which makes for a very distinctive and aesthetic specimen. Accompanied by some smaller side crystals this construct sits on a piece of rock matrix, sparkling with pyrite at the backside. A very nice and 3-dimensional specimen from the Cavnic Mine, all elegant and in good condition.

Bright neon-yellow color and perfect textbook-aeshtetics join together on this classic sulphur specimen. It has become increasingly hard to obtain high class sulphur from Sicily thus I am happy to present such a great piece here. It is a cluster of several gemmy crystals on a small amount of crystallized white aragonite at the bottom. The piece is in very good condition with only some minor edgewear which is actually remarkable on a sensitive mineral as this. Truly a striking specimen of best color and perfectly attractive arrangement!

Incredible, juicy, cranberry-red color radiates from this fine specimen even at low illumination, waiting to explode at direct backlight. The color you see in pictures and video is not exaggerated at all! The spessartine has just the fantastic quality the Navegadora claim is famous for. Its 3-dimensional shape feels very much alive and is complete on front and backside. Being a perfect floater this fine piece is perfectly crystallized on all sides and is almost flawless save for one small chip at the backside. A great piece of superb aesthetics and utterly gemmy spessartine!

The brookite crystal on this lovely little specimen is a stunning 2.3 cm long and shows best maroon color with the characteristic hourglass painting. The dominant crystal is associated with some quartz, beautifully arranged around the brookites base. A side-crystal at the back is broken but which is long re-healed and not visible from the front anyway. Fantastic aesthetics, highest crystal quality and a flawless condition make this floater from the worlds best brookite locality a total stunner!
