Marquise Lab-Grown Diamonds
The marquise is an elongated brilliant with points at both ends, cut to maximise surface area, so it faces up larger than almost any brilliant shape at the same carat weight. Its boat-like outline dates to the court of Louis XV.
Both points need protecting, and the bow-tie shadow across the centre is worth checking; a length-to-width near 1.90 usually gives the most balanced outline. Lab-grown diamonds are chemically, physically and optically identical to mined stones, certified to the same standards and typically 60-80% less per carat. Our lab-grown diamond guide covers the detail. Compare it with every other outline in our diamond shapes guide, and get to grips with what actually drives price in our diamond 4Cs guide. All our stones carry independent laboratory certification and transparent pricing, and our London team will talk you through any of them with no obligation.
