There are many hypotheses about the formation of this stone, but all seem to be incredible.
The size of these things ranges from a maximum of 3 cm (1.2 in.) down to an incredible 0.003 mm, about 1/10,000th of an inch!
To date, these inexplicable artifacts have been found in their thousands at various sites near the rivers Narada, Kozhim, and Balbanyu, and also by two smaller streams named Vtvisty and Lapkhevozh, mostly at depths between 3 and 12 meters (10 and 40 ft.) The spiral-form objects are composed of various metals: the larger ones are of copper, while the small and very small ones are of the rare metals tungsten and molybdenum. It is used principally for the hardening of special steels, and in unalloyed form for the filaments of light bulbs. This metal too is used for hardening steels and giving them corrosion-resistant properties, these being used principally for highly-stressed weapon parts and vehicle armor.
Roughly half have 6 knobs---like the one at right above---but the others range from three to 160 knobs.
The more mathematically regular ones do not appear to have had a special importance.

In the years 1991-1993, gold prospectors on the small river Narada, on the eastern side of the Ural mountains, have found unusual, mostly spiral-shaped objects.
However the Parthians were skilled warriors rather and their scientific achievements were not known.
