The name was introduced by d`Andrada in 1800 for a mineral found at the Hellesta (?) and Åssebro (?) iron mines in Södermanland, Sweden and the Arendal iron mines in Norway. It was later showed to be identical with diopside. The name is derivated from the greek words for grain, κοκκος, and λίθος, rock, and it occured as massive granular concretions of anhedral to subhedral grains, loosely aggregated together, and frequently separated simply by the press of a finger.

May also be an alternate spelling for coccoliths, individual plates of calcium carbonate formed by algae arranged in a sphere.
A synonym of Diopside
