The main 4.7 cm aquamarine crystal is a completely glassy, decently blue and with a complex, frosted termination. It is set on a pristine white feldspar matrix with associated aquamarine side crystals and black schorl at the backside. The piece is in fact a floater with chloritizations at the bottom. There are some contacts present but especially the aquamarine including the side-crystals is all perfect and complete! Nice aesthetics, high crystal quality and near flawless perfection!
Composition and crystal quality and overall aesthetics are absolutely amazing on this magnificent garnet specimen! One single spessartine crystal, 2.8 cm in diameter and of cherry red color, is set atop a contrasting white feldspar floater. To fatten things up even more there is a complex doubly terminated schorl at the garnets backside. Absolutely beautiful in person! At the spessartines front tip you can see an old and re-heald chip but which is the only small issue on this otherwise perfect and super-aesthetic specimen!
A combination of golden chalcopyrite up to around 2 cm in diameter and some cubical pyrite on a contrasting background of white quartz. All is very nicely developed and in best condition. A classic from this centuries old mine!
Deep strawberry red color, topped by a zone of satiated green strikes as the heart of this fabulous tourmaline specimen! The thick single crystal is gemmy and highly lustrous on all sides with nice striations and small attached side-crystals. Right beneath the mirroring flat termination is a very thin zone of intensive pink color that adds a surprising visual effect when seen from the side. Absolutely stunning in person! There is some minor edge wear present but the overal condition is very close to perfect!
A beautiful combination of fluorite and barite with great aesthetics! The intensively purple and glassy fluorite comes as well developed cubes with elegant bevels. The crystals are flawless and also crystallized at the back. White tabular barite forms a wonderful base for the fluorite and makes this an aesthetic highlight of perfect proportion and high quality!
Found in spring 2014 this specimen is a fine example for the extremely rare species of Opal-CT (tridymite crystobalite opal). The striking turquoise Paraiba-color is caused by copper and catches the eye instantly. The main view is impressive for its strong color and the sheer rareness of this material. Absolutely outstanding on an international level!
Never would I have thought that a single crystal schorl could be as fascinating and unique as this very specimen! Unlike most crystals this is not just a plain prism with some striations but much more a complex stack that looks as if it was constructed from many smaller parts with only the upper half being more straight forward. Jet black color, superb luster and the richness in details provides and elegant and somehow mystic feel to this impressive crystal. The hexagonal shape ends in a bevelled flat termination. Very beautiful in person and really something special for the material!
It's a typical tabular barite specimen composed of translucent crystals with a waxy luster. The somewhat blueish crystals show yellow inclusions of what might be limonite. A nice piece in overall very good condition!
With a size of 3.5 cm the vivianite main crystal here is not the biggest we have seen but the quality is stunning in person! There is best wet-look luster around a gemmy, completely limpid and sharply defined crystal! The open blueish-green color contrasts to the warm brown matrix. Behind the main vivianite the matrix extends three-dimensionally backwards where a number of smaller, equally perfect vivianites is places. This is an amazingly beautiful and appealing specimen from this world famous region!
While the individual crystals are rather small (the largest reach a little over 4mm on edge) this whole rock is very nice and crystallized on all sides which invites you to turn it around in your hand. The amber-brown and at some part white crystals cover a metallic black matrix that is visible only at the bottom. There is no damage anywhere so this is a charming piece with no downsides!
This distinct gold specimen is out of the famous 2015 find in Mato Grosso. Best color, filigree growth and a vibrant sheen are trademark for this locale and are main feature of this very specimen. As most of those specimen this piece is a floater and very much 3-dimensional in shape. Beautiful and elegant growth patterns are visible all over the gold and make for a absolutely staggering elongated sculpture that looks like an artfully carved pillar. Beautiful and marvelous!
This miniature features a single carrolite crystal at the center of a white calcite matrix. The calcite is lustrous at the lower parts and covered in a fine layer of chalcopyrite micro crystals further up. The carrolite is a perfect cubo-octahedral crystal of bright silver luster with a size of around 1 cm in diameter. A lovely little specimen of this splendid mineral!
