It's hard to imagine how a single crystal could be better emphasized on a specimen! The intensively purple fluorapatite is set on a massive blueish black tourmaline matrix that is covered in a cream-colored layer of mica microcrystals. The apatite is gemmy, highly lustrous and virtually perfect. When you turn the piece around you can see the massive black tourmaline that is mostly opaque but has some gemmy blue patches too. Definitely an unusual yet remarkable specimen!
The well defined, gemmy, lustrous zircon crystal with golden amber color is set on a white calcite matrix. The single crystal is very well emphasized against the contrasting matrix which is actually quite uncommon for this rare mineral. The crystal gets even more intense at direct downlight which easily brings out the wonderfully appealing color! A beautiful crystal in very best condition!
A single tourmaline crystal from the Ampanivana pegmatite that shows nice strawberry red color at direct backlight illumination! The crystal is flawless with a richness of details: nice surface structure, white spots of associated albite, attached side-crystals and a modified flat termination. There are some contacts but everything is re-crystallized and not broken.
A single main spinel crystal is set on a glistening white matrix that's sprinkled with smaller spinels all over. The main crystal is 2.2 cm broad, translucent and with a deep strawberry red color that is especially strong if you add some warm light from the back or top. The spinel has the usual rounded edges without loosing its well defined shape that is a flattened modified octahedron.
Diamantina is well known for its quartz specimens with inclusions of rutile, hematite or chlorite. However, this very distinctive smoky quartz sceptre is a brilliant exception. The aesthetics is very straight forward: A large head of nice smoky color is grown on a colorless stem, both of which show very fine luster and sharp development. At the touching point between stem and head there is a dark zone that is particularly smoky! The overall condition is very good with only a contact at the backside and some contact induced rough edges. No damage!
Among the many gold pieces that came from the rich finds at Serra do Caldeirão, among the rich shapes and patterns of finest bright gold, this thumbnail sized specimen strikes with exceptionally pronounced hoppered growth, visible on both front and backside! That makes this piece not only unique and rare but also immensely attractive in person! There is no damage or contact at all.
The contrast of black huebnerite and white quartz is quite striking here, especially as all crystals show very best sparkling luster! While the backside has some damaged crystals you will hardly find any flaws when looking at the attractive main view. The huebnerite comes as sharp and lustrous prismatic crystals that are mostly black but with some fire-red patches here and there if you add direct backlight. A rich and lovely piece of beautiful aesthetics!
This small thumbnail specimen shows ideal aesthetics, best quality and is in outstanding condition! The single doubly terminated anatase crystal is 1.3 cm long, lustrous and flawless. It has a small patch of limonite at the backside which adds some rust-brown color to the otherwise black and white specimen. The crystal is set on a sparkling white cluster of pure quartz that is in fact a complete floater without damage or contacts! All in all this is a remarkably lovely specimen with no downsides!
The mix of calcite, galena and chalcopyrite is not only a characteristic paragenesis for the locale but it's also a vibrant combination. White scalenohedral calcite crystals up to 6.5 cm are set on a landscape of metallic black galeny embedded in white calcite and golden chalcopyrite microcrystals. The specimen is quite stunning in size and shows overall very good quality and condition!
Rose quartz of marvelous pink color forms this fine vug-like specimen! As a complete floater this piece is crystallized all around - with rose quartz mainly but also with an association of smaller white quartz crystals on the backside which adds a nice contrast! Its an unusually fine rose quartz specimen in best condition!
Brilliant glassy quartz crystals are three-dimensionally arranged along a white thread that runs right through the center from bottom to top. The combination of crystals in different dimensions makes this specimen rich and vibrant all around! The whole speciment is without damage and beautiful on all sides!
It's an elegant sculpture of bright yellow brucite on a small piece of rock matrix. The brucite shows very best color and quality with wonderful luster and transparency! It is perfect all around which is hard to imagine on a delicate piece like this. An exceptional and highly appealing piece of this bright mineral!
