The marquise that pulls a second look across a room is doing it through the way the elongated outline catches indoor light along its long axis, producing moving flashes that round solitaires do not. A 1-carat marquise also covers about as much finger as a 1.5-carat round at the same ratio, which is one reason buyers who came in looking for an oval leave with a marquise instead. The six designs below earn the turn-head label because each studio has made a deliberate choice on cut, setting, or stone supply that a stranger can see from six feet away.
