The first clue to the presence of possible diamond-bearing source rocks in northern Alberta was the discovery of a perfect octahedral diamond, estimated at about 0.83 carats in weight, by farm worker Einar Opdahl during 1958 in the Evansburg area of west-central Alberta. Since the Opdahl diamond, no new diamond finds were reported in northern Alberta until the 1990s, when several occurrences of alluvial diamond and diamondiferous kimberlite were discovered.
