2nd Sovietskii Mine (2nd Sovietskiy Mine), Dal'negorsk (Dalnegorsk; Tetyukhe; Tjetjuche; Tetjuche), Primorskiy Kray, Far-Eastern Region, Russia A gorgeous combination cabinet piece consisting of pale pink flattened rhombohedral crystals of calcite to 2 cm in size draped attractively about a matrix of black lustrous crystalline sphalerite. This is very clean of damage; I cannot find any chipping even with my 10x loupe. The crystals are nicely arranged and contrast nicely upon the black ... |

2nd Sovietskii Mine (2nd Sovietskiy Mine), Dal'negorsk (Dalnegorsk; Tetyukhe; Tjetjuche; Tetjuche), Primorskiy Kray, Far-Eastern Region, Russia 6.4 x 4 x 3 cm. This is a VERY unusual Dal’negorsk calcite, due to the extremely uncommon tabular form of the two main “rabbit-ear” crystals (3 cm). The pocket conditions must have been bizarre, because at the feet of these crystals are several crystals that are almost opposite in form: extremely truncated, fat and stumpy, far wider than ... |

2nd Sovietskii Mine (2nd Sovietskiy Mine), Dal'negorsk (Dalnegorsk; Tetyukhe; Tjetjuche; Tetjuche), Primorskiy Kray, Far-Eastern Region, Russia An intricate, complex, twinned calcite crystal that is nearly a complete floater, with just a small attachment in the bottom -rear. The symmetry and patterning, in person, is really mesmerizing and this is unlike anything I have yet seen from Dalnegorsk! MUCH BETTER IN PERSON. I know it LOOKS curvy and cockeyed atop, but that is a visual illusion ... |

2nd Sovietskii Mine (2nd Sovietskiy Mine), Dal'negorsk (Dalnegorsk; Tetyukhe; Tjetjuche; Tetjuche), Primorskiy Kray, Far-Eastern Region, Russia A very unusual specimen consisting of black rhombohedrons forming an arboreal arrangement with second generation hexagonal prismatic crystals with pinicoid terminations. The coloration is caused by inclusion of an unknown mineral.7cm X 3.5cm X 3cm |

2nd Sovietskii Mine (2nd Sovietskiy Mine), Dal'negorsk (Dalnegorsk; Tetyukhe; Tjetjuche; Tetjuche), Primorskiy Kray, Far-Eastern Region, Russia 3.5 x 2 x 1.8 cm. An absolutely terrific Dal’negorsk calcite mini, a perfect “nail-head” crystal with fine transparency, a perfect pyramidal termination, and a bit of accenting matrix attachment. As a bonus, there is a very noticeable phantom down towards the bottom – you can see its striated termination clearly inside. |
