Old Mine Cut


1 A trade term that is applied properly to an early form of brilliant cut with an early square or cushion-shaped girdle outline.

2 A term applied occasionally and incorrectly to a somewhat more modern style of brilliant cut that also has a much higher crown and smaller table than the modern brilliant cut, but whose girdle outline is circular or approximately circular- a style of cutting that is more properly called a "Lumpy Stone" or "Old European Cut".
