Type Locality:

Colour: light pink

Description: Kumtyubeite is noted in spurrite-rondorfite-ellestadite zones of skarn, developed along the west contact of the xenolith. In hand specimens of the grayish-reddish matrix, kumtyubeite forms oval spots up to 1 cm across, composed of light pink grains 250 µm in maximum dimension. Kumtyubeite was also identified in another paragenesis in xenolith 1, associated with bultfonteinite, and intermediate compositions of the reinhardbraunsite-kumtyubeite series have been identified as rims on spurrite grains.
