Diamond occurence relates to the crust of weathering of eclogites and garnet-muscovite schists. Some garnet grains were found in the crust of yellowish-green colour.
Octahedral diamond crystals 0.5-1.6mm in size were found in eclogite weathering crust and crystals more than 1mm were found in garnet-pyroxene rocks.
Fragments of crystals (2.95mm) are found in sands of Kumdykol lake. Gem-quality diamond 1.9mm across was recovered from the sands.
