Kester Deposit, Arga-Ynnakh-Khai granite Massif, Yana-Adycha Region, Yana River Basin, Verkhoyansk, Saha Republic (Sakha Republic; Yakutia), Eastern-Siberian Region, Russia Fragment of large monograin of fresh, translucent Amblygonite with inclusions of smoky Quartz crystals. Unusual marine-green colouration is caused by thin films of later formed Arthurite, which is well visible on the right and left edges. Small triangular spot in upper part of the specimen is pseudomorphose after Kesterite crystal, now it is ... |

Kester Deposit, Arga-Ynnakh-Khai granite Massif, Yana-Adycha Region, Yana River Basin, Verkhoyansk, Saha Republic (Sakha Republic; Yakutia), Eastern-Siberian Region, Russia Fragment of large monograin of fresh, translucent amblygonite. Unusual marine-green colouration is caused by thin films of later formed arthurite, which is well visible on the right edge. Specimen size is 6.3x4.5x2.7 cm. Most of "amblygonites" from different pegmatites in reality are montebrasites or members of montebrasite-amblygonite series ... |

Kester Deposit, Arga-Ynnakh-Khai granite Massif, Yana-Adycha Region, Yana River Basin, Verkhoyansk, Saha Republic (Sakha Republic; Yakutia), Eastern-Siberian Region, Russia Cleavage surface of large monograin of fresh, translucent amblygonite. Specimen size is 5x2.7 cm. Most of "amblygonites" from different pegmatites in reality are montebrasites or members of montebrasite-amblygonite series from montebrasite side. In other words, most of pegmatitic "amblygonites" are too unsaturated with fluorine to be ... |
