Using gases trapped within natural diamonds as detected by crushing in the sample system of a research mass spectrometer, a proposed gaseous environment for the formation of diamonds is presented. Diamonds crushed under a vacuum of 10-9 torr at a temperature of 200℃ yielded, in order of abundance, water, hydrogen, nitrogen, carbon dioxide, methane, carbon monoxide, argon, and ethanol.
