Author's Material 

This specimen is from Dr. Igor Pekov's study material.

Virtually all of the bright green crystalline areas on this specimen is Ericlaxmanite. Very few of these specimens were collected by the team of geologists from Russia including Dmitriy Belakovskiy and Igor Pekov. The team took fascinating videos while collecting on and in the  scoria cone vents under extremely hot and toxic conditions. The remoteness and altitude alone are enough of an obstacle to keep most serious collectors away from this place.  Type material is deposited at the Fersman Museum in Moscow and the new mineral was published in Mineralogical Magazine 77, 2695-2709.

This piece shows a whole lot better in-person than online. It is a wonderful specimen with ice-like luster and aqua color. It is nicely translucent with a neat network of internal cleavage lines. Each crystal has beveled edges, which carry a nice frosted finish. The largest crystal is to almost 6cm and attached to this crystal are six smaller crystals. No damage, sweet piece.

Nickenichite is named for the village of Nickenich, Germany and nearby the Nickenicher Sattel volcano. At this locality, it also occurs in volcanic fumarole rich in vanadium vapors. This specimen contains, beautiful deep azure blue micro crystals to about 1mm. This is the second worldwide occurence of this rare arsenate far superior to the type locality.  It is verified by Dr. Igor Pekov.

The exact locality is: Arsenatnaya fumarole, Second scoria cone, Northern Breakthrough, Great Fissure eruption (Main Fracture), Tolbachik volcano, Kamchatka Oblast', Far-Eastern Region, Russia

A colorful, choice specimen of purple crystal groups of Strengite measuring 1 to 2mm on Cacoxenite which forms balls and cross-sections of golden fibers. Outward from the cavity is dull green Kidwellite and finally lining all this is deep red Beraunite. I love these combination specimens from the York mine. They are simply some of the best assemblages of phoasphate minerals you'll see.
