Boleite is an extremely rare copper-lead chloride that is almost exclusive for Mexico. This piece shows a rich ore of cubical boleite up to 0.5 cm on edge, with strikingly intensive indigo blue color and great luster. The crystals are translucent at direct illumination and very well situated on a piece of crumbling matrix that provides a stark contrast. The backside of the rock - but also in smaller amounts the whole piece - holds green paratacamite as well. A visually attractive piece for this rare mineral!
Bou Azzer is easily the most famous and rich source for high class erythrite specimens worldwide and has produced collection pieces since the 1960s. This specimen is an old classic of superb quality and captivating appearance. A piece of grey rock that is covered in brilliantly lustrous and gemmy erythrite crystals on half its surface. The sharp crystals are very much stacked together, reaching around 1.2 cm in length. Overall this piece is in great condition with only some peripheral issues. An impressive piece altogether, elegant and appealing!
It is a highly attractive combination of white quartz with embedded olive-brown siderite rhombohedrons. The coronal arrangement of the sharp and lustrous siderite crystals makes for a very much enjoyable view in person! The high quality piece is in very good condition with no visible damage anywhere. Some rough edges are due to natural corrosion but not worn or damaged. This is a real classic and nicely aesthetic for sure!
Unlike the more common acicular crystals of chalcanthite, this specimen features a single sharply terminated and gemmy crystal of deep blue color on matrix. The chalcanthite is 5 mm across and well emphasized by its strong, piercing blue color. Small but unusually well shaped!
The piece comes from Zagi Mountain in Peshawar, Pakistan where the best and largest crystals of bastnäsite have been found worldwide. It has distinctive aesthetics with two hexagonal prismatic crystals on a contrasting feldspar matrix. The crystals show a warm amber color, are part gemmy and lustrous. The more prominently situated crystal on the left is doubly terminated and flawless with a length of 1.2 cm. The second crystal is a stunning 1.5 cm long which is very well visible even though it is partly embedded in matrix. A perfectly attractive specimen with no damage and great composition.
The piece is out of a new find and it is 100% lovely. It is incredibly aesthetic with a cluster of rich pink fluorapatite on a perfectly contrasting white albite matrix. The apatite is highly lustrous, sharp and shows unusual crystal habit. The piece is complete all around, with contacts at the bottom but no damage. Small edgewear is present but not apparent. Definitely a marvelous piece, very elegant and with no downsides. A real jewel!
A beautiful and classic specimen of chalcopyrite and sphalerite from the Krushev dol deposit in Bulgaria! This piece is a floater and 360° well crystallized with charming golden to brown, in parts even purple chalcopyrite studded with black tetrahedral sphalerite crystals. It is of nice cabinet size and lies heavily in hands. At the lower parts there is some damage here or there but nothing to really worry about. The outline is all perfect and shows great contrast and color. A staggering piece in person.
Tsumeb is well known for its worldclass malachite pseudomorphs after azurite. This however is a beautiful piece of botryoidal primary malachite, towering like a coral on a reef of white calcite, which is nicely crystallized on the backside (mind our video!). The whole thing is a floater, very delicate and in great shape. An uncommon specimen from the famous Tsumeb mine!
A classic Tsumeb style azurite from the worlds most famous Mine for collection minerals. Two thick and gemmy azurite crystals are perched on a piece of matrix, diagonally leaning against each other. The frontside shows spectacular luster and a strong blue color. The backside is naturally eroded but still very attractive in its own way. There are some chips here and there which sure reduce the price on this, but the overall shape is intact and attractive. Not perfect, but definitely a worthy and appealing specimen!
I just recently got this marvel out of the lab and I must say I am overwhelmed! The rather large hematite rose dramatically sits atop a white contrasting albite matrix of stunning sparkling quality. The hematite itself is 3.3 cm in diameter and massive 1.2 cm thick, all perfect and of brilliant luster. I totally love the aesthetics of this very well balanced piece that is a real eye-catcher in person and free of any damage. If you look closely you can even make out some small apple green titanite among the albite. Absolutely outstanding and impressive!
A doubly terminated single crystal that is impressive 12.3cm in size! It has the characteristic dark metallic black color with a greenish sheen to the surface. The crystal is completely flawless and remarkably elegant, sharply developed and with a small amount of orthoclase to one of the faces, as is characteristic for the locale at Mt. Malosa. It dates back to the early mining period in Malawi, where first considerable aegirine crystals have been found 25 years ago and is absolutely outstanding in person!
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 sculpture. Lovely and marvelous!
