IIRC the cutting styles developed OEC -- European Cut -- Transitional Cut. ECs were a flash in the pan compared to OECs.
Let me see if I can find something semi-reputable online...here you go:
European Cut
Obsolete. A diamond brilliant whose proportions were worked out mathematically for light falling perpendicularly on the crown. It was never adopted as a common form of cutting. The angle of the pavilion facets to the girdle is 38° 40’; of the bezel facets, 41° 6’. The table is 56% of the girdle diameter; crown depth, 19%; and pavilion depth, 40%. It is not to be confused with the old European cut.
