Data on cubic diamonds with a very restricted delta C-13 range, a relatively high and constant nitrogen content, and low nitrogen aggregation state, from the Orapa kimberlite are analyzed. Results confirm the conclusion of the earlier studies (Deines, 1980; Deines et al., 1984, 1987, 1989) that a multitude of diamond sources and formation processes must be considered for the formation of diamonds recovered from any kimberlite.
