It crystallizes in the orthorhombic crystal system (space group Pmnn).

IMA symbol Kdy, IMA status: approved, named in 2007.

Occurs as inclusions in omphacite in eclogite (Kazakhstan). Presumed to form under high temperatures with rapid cooling and in the absence of water. As inclusions in garnet in a diamond- bearing.

It is found associated with Diopside, quartz/cristobalite, phengite/phlogopite, calcic amphibole, dolomite, calcite, talc, omphacite (Kazakhstan); phlogopite, quartz (Bohemian massif).

The name refers to Kumdy Kol, the source of the first specimens.
