This rose quartz specimen has a unique circular shape with sparkling crystals fanning out from the center.

YC873 - Quartz on Wulfenite - Sold
M’Fouati Mine, M'fouati District, Bouenza, Republic of Congo
Size: 6.2 x 5.8 x 3.9 cm
Watch Video
 
 
 

Wulfenite from M'Fouati has never come onto the market in large quantities but what has been found in the late 50s and early 60s counts among the finest wulfenites of the whole continent. This is a superb wulfenite from that period that impresses with great orange color and sheer size - it is 27mm across!
Tiny, appealingly sparkling Quartz crystals cover a large part of the crystal but where the wulfenite is free it is highly lustrous! The crystal is complete all around with no contacts or damages at all. The red-brown gossan matrix is covered in sparkling quartz too and provides a superb contrast and background for the dominant yellow-butterscotch crystal!
It's a rarity of striking aesthetics and outstanding dimension and a mayor piece for the locality!

This is a wild mix of green augelite and white quartz from the Mundo Nuevo Mine, famous for the worlds best augelites. Among the number of small scale specimens we have seen from the locale this one stands out with a size of 8.7 cm in total. The largest augelite is 2.2 cm long and part of a augelite aggreagate of intensive apple green color. The crystals are sharp and undamaged and with very nice luster. The quartz comes as white to transparent elongated crystals, some of which show japan-law twinning. The overall condition is very good, even the backside is crystallized with quartz micro-crystals.

Large transparent brown phologopite crystals with contrasting white marble. The main crystal is stunning 5.5 cm broad which is really gigantic for the mineral! It is very easily lit, has a warm brown color and is complete all around. Some crystals on this specimen are in fact cleaved (not so the main crystal) but which is not so obvious and doesn't compromise the overall aesthetics. This is a remarkable specimen for this rare mica variety!

This piece is really something special for the material that shows brilliant, sharp and gemmy strawberry red crystals with superb luster! The whole specimen is complete and undamaged with crystals richly distributed about front, back and just everywhere in between! The matrix is a solid rock that is partly covered in white barite which is a very attractive background for the gemmy vanadinite crystals!
Among the many pieces that have come from the locale in Mibladen in Morocco, this really stands out for its exceptionally high quality and the beautiful aesthetics!


SU11 - Topaz - 1250€
Fazenda do Centro, Castelo, Espírito Santo, Brazil
Size: 14.7 x 12.3 x 7 cm

This large and heavy etched topaz is quite dominant with a bright glassy interior! At the base it has an interesting structure that looks as if some thin tabular mineral was grown into the topaz but it might as well be some form of dissolving pattern. The upper two thirds of the crystal are clear and with lovely etchings and beautifully structured surface. On the negative side this piece has a damage on the left side (you can better see that in the video) as well as some abrasions. Despite this issue this is still a very impressive exemplar from this spectacular one-time find!

This very fine tourmaline specimen was part of a new find at the Chia Mine near Sao Jose do Safira. What’s special here is the exquisite quality and intensive color of the tourmaline! A deep cherry red core is coated by a layer of striking emerald green which defines the color-play of this piece. Additionally there is pink lepidolite present adding much to the beauty of this specimen!
The overall condition is very good but there are a couple of well done repairs. A very striking piece in person that offers great quality and nice aesthetics!

The colorful combination of purple amethyst with crimson red hematite inclusions is uniquely beautiful and utterly fascinating in person! The inclusions on this specimen are especially rich, concentrated at the tips of the short pyramidal quartz crystals. With some backlight you can very nicely see the different zones of white quartz at the core, purple amethyst and fire red hematite inclusions towards the tips. The backside is completely crystallized and the overall condition is excellent.
The Moon Light mine is one of the lesser know localities at Thunder Bay as there is no public collecting allowed there. This specimen however is a beautiful exemplar from this rare occurrance!

The largest calcite is a 5.3 cm doubly terminated crystal, prominently set at the very top. It is supportet by a complex aggregate of smaller crystals, all covered by brilliant chalcopyrite.

VK574 - Stibiotantalite - 650€
Dara-i-Pech pegmatite field, Chapa Dara District, Kunar, Afghanistan
Size: 1.5 x 0.9 x 0.5 cm

Stibiotantalite is an extremely rare antimony tantalum niobium oxide that usually comes as dark brown to reddish crystals, often opaque and unattractive. In some exceptional cases however stibiotantalite develops well defined crystals with bright gemmy yellow color!
This crystal is exactly that and despite the rather small size it is an impressive piece for the material that shines with great crystal quality and a superb and flawless termination!


US684 - Amethyst - 2200€
Ametista do Sul, Alto Uruguai region, Rio Grande do Sul, Brazil

Really amazing here is the clear, elegant and simply beautiful aesthetics. Unlike the usual geodes that come from this region this specimen was discovered as a freely grown, extremely well crystallized specimen which is rare and stunning already! The solid main crystal with brilliant quality and very strong purple color at the sharp pyramidal termination stands at the center of bright and glassy side crystals fanning out around its base. The overall quality is absolutely superb and there is hardly any abrasions except for maybe one or two peripheral dings.
I was able to get this one from Munich based collector Malte Sickinger who had it on display at the special exhibition at the 2019 Munich Show.
