At 1 carats, a D color old mine marquise is colorless, meaning it is absolutely colorless with no detectable warmth. Only detectable by trained gemologists with master stones. In white gold or platinum, D color faces up clean and bright. In yellow or rose gold, any faint body color becomes imperceptible against the warm metal. The old mine marquise cut's antique brilliant facets create elegant reflections of the metal color.
