MD-112552 - Tsaregorodtsevite - - Archived Yaruta Mt, Man'-Khambo Mts, Khanty-Mansi (Khanty Mansiysk) Okrug, Polar Urals, Western-Siberian Region, Russia small cabinet, 6 x 3.7 x 1.8 cm
Tsaregorodtsevite is a VERY STRANGE mineral that is made up of AMMONIA with nitrogen, and an aluminosilicate compound. I recall when Fersman Museum started selling their extras in 1991, this was one of the most coveted of all rare species that came out the doors from their various expeditions. I got some directly at the time from curator Dmitriy Belakovskiy, who has himself been to this remote location on at least one expedition. I assume this specimen came form teh same source, the only source so far as I know. I have owned several over the years, and I can say this is a very good and rich specimen. It has crystals to 4mm. 6 x 3.7 x 1.8 cm

5.3 x 4.6 x 4.3 cm. Tsaregorodtsevite is a very rare and very strange aluminosilicate mineral that contains the tetramethylammonium ion. This sodalite group mineral is found at ONE locality, worldwide.

I assume this specimen came form the same source, the only source so far as I know. I have owned several over the years, and I can say this is a SUPER and RICH specimen. It has lustrous and gemmy, pseudocubic crystals to 5mm on chlorite mica schist.
MD-148322 - Tsaregorodtsevite - - Archived Yaruta Mt, Man'-Khambo Mts, Khanty-Mansi (Khanty Mansiysk) Okrug, Polar Urals, Western-Siberian Region, Russia small cabinet, 7.1 x 2.6 x 2.2 cm.
7.1 x 2.6 x 2.2 cm. Tsaregorodtsevite is a VERY STRANGE and UNIQUE mineral that is made up of AMMONIA with nitrogen, and an aluminosilicate compound. I recall when Fersman Museum started selling their extras in 1991, this was one of the most coveted of all rare species that came out the doors from their various expeditions. I got some directly at the time from curator Dmitriy Belakovskiy, who has himself been to this remote location on at least one expedition. I got this from him a few years ago because he remembered I liked them, and have forgotten to sell it ever since unfortunately. I have owned several over the years, and I can say this is a very good and different specimen because it actually has some display aesthetics that most lack. Two pseudocubic crystals, to 4 mm, are set on the side of a glassy, water-clear quartz crystal, which is heavily included with chlorite. There are also a couple of tiny anatase crystals, on the same side, below the tsaregorodtsevites. The quartz termination is lightly bruised, but is certainly not a detraction to this RARE combo piece. Found in ONE locality, worldwide.

I assume this specimen came form the same source, the only source so far as I know. In fact, I bought this piece from him at Tucson 2008, surprised to see another turn up after so long. The perch on a quartz cluster makes the display here particularly good - usually these are on flat gray rocks.
