* slag

This beautiful slag is the rarest mineral in the whole world, a pure unique, because it can only be found in one place in the world, in the place of an old metal smelter, from the time of the ROMAN EMPIRE - ANTIQUITY (about 2000 years), and perhaps even earlier, when warrior ILLIRIAN TRIBES also lived at the place of discovery, who had excellent processing of iron weapons !!

In those old times, the slag was not as poor and drained as it is today, but it contained a lot of silicon, but also a lot of metal that was not used then, along with iron, copper or some other ore that was used in that smelting process.
ok
A small part of that old slag is extremely beautiful, almost identical to one of the known types of obsidian, because it is an amorphous, glassy material, with a certain kind of transparency and excellent shine (which we can attribute to zinc or nickel ores, which were found on the nearby volcanic mountains).

Snow Obsidian :
Between the glass parts of the stone, there is a larger amount of basalt structures of small gray clusters of crystals.

(Betwen, a beautiful amorphous/vitreous material, it is crossed by a branched branch/vein of gray basalt, which has a crystalline structure on the surface.)

This diamond slag is even more beautiful than obsidian, since it contains more or less inclusions of beautiful opalized minerals (precious stone PERIDOT or ZINCITE), which most often sparkle with yellow sparkles, but also in rainbow colors !!

The price of such valuable and unique minerals should at least equal the price of obsidian, and that will happen soon, since zinc slag crystals are already sold that way - ZINCITE !

All other checks of the physical characteristics of this mineral will be published soon.
