The marquise cut is an impressive cut with plenty of history . The name marquise refers to a hereditary rank above a count but below a duke and comes from courtiers wearing marquise cut diamonds in order to show off their rank. Marquise cut gems are also often referred to as navette, which means little ship in French, because of the marquise boat-like shape. We have set a stunning 14.09ct of marquise cut Daniel Steiger created Diamondeau, our exclusive substitute for natural diamond in the center. A truly impressive statement trilogy ring.
