ALROSA, Russia's largest group of diamond mining companies, uncovered a mysterious Russian rock containing 30,000 tiny diamonds.

The sparkling red and green rock was unearthed in the massive Udachnayaa diamond mine in Russia and was donated to scientists for analysis. They diamonds studding the rock are so small that they're worthless worthless money-wise.

Researchers admit they're clueless as to how these tiny diamonds were formed while the origin of strange rock is particularly enigmatic.

The strange red and green stone measures 30 millimeters, which is the size of an ornament, and has a concentration one million times higher than normal. The rock is octahedral in shape. The red and green color comes from larger crystals of garnet, olivine and pyroxene.

Geologist Larry Taylor at the University of Tennessee, Knoxville believes the diamonds somehow formed instantaneously.

"The associations of minerals will tell us something about the genesis of this rock, which is a strange one indeed. The [chemical] reactions in which diamonds occur still remain an enigma," Taylor said.

Based on X-ray results, researchers suggest the diamonds crystallized from fluids that escaped from subducted oceanic crust, and are likely composed of a dense rock called periodtite.

The findings will provide scientists with important clues about the Earth's geologic history and the origin of these prized gemstones.

The latest research findings will be published in January 2015 in a special issue of Russian Geology and Geophysics.
