The occurrence was discovered in 1989. It is composed of ultrabasic rocks, alkaline gabbroids, phlogopite-diopside skarnoids and eruptive breccias. The breccias contain the fragments of clinopyroxenites (with garnet and apatite), alkaline syenites, leucite lamproites, garnet micaceous schists, leucities, shonlinites and biotite monchiquites.
The diamond samples were recovered from breccias, in some samples individual finest (0.01-0.05mm)diamond grains. The colours were mostly yellow, yellowish-green, crystals had deformed octahedral shape.
