El'tigen - Ortel'skoye mestorozhdeniye, 2 Chernomorskoye, Kerch', Ukraine
Mass: 561 g
MIM number: 2263
A 3 cm honey-brown barite ball is beautifully placed in a vug resulting from the fossilization of a bivalve (which shape can still be seen) amidst a plethora of translucent, sea-green anapaite tufts. Anapaite is a very rare phosphate: the elements calcium and phosphorus needed to form this species are derived from the fossilized shell material (the initial calcite of the shell still appears in patches outside of the latter), while iron comes from the iron deposit of sedimentary origin in which the bivalve fossilized.

Large plate formed of ten very well-formed crystals of smoky quartz (the largest measuring 20 cm), slightly bluish albite blades and lepidolite on which a huge crystal of green tourmaline has formed in a tilted position with several other smaller crystals. The large crystal is translucent on the surface with a deep bottle green color, while the small crystals are transparent. All tourmaline terminations are pointed, some being fibrous. It is remarkable that such an assemblage formed and survived virtually intact, especially in this mine where this is not the usual type of production.

MIM number: 2269
Large cluster of bright crystals in subparallel formation. These very well-formed crystals resemble cogwheels (which is the characteristic twinning of this species) giving this sample the appearance of a gearbox, hence its nickname, "The Gearbox". It is remarkable that such a large plate could be recovered intact, knowing that bournonite is a very fragile mineral. This is one of the largest and best groups of this mineral found in Bolivia.

Large mass of black lamellar hematite studded with lustrous crystals of pentagonal dodecahedra shaped pyrite. In the center of the sample is a well formed 7.5 cm wide "iron cross" twin resulting from the 90 degrees overlapping of two dodecahedra. It is surprising to see in the same sample equilibrium domains where sulfur can give compounds in its least oxidized state (as in pyrite, FeS2), and where, simultaneously, iron has its highest degree of oxidation (as in hematite, Fe2O3). The deposits of the island of Elba and of Tuscany constitute the basis of the Etruscan iron industry and are thus at the origin of one of the oldest civilizations that used iron.
