About this 0.73ct lab-grown marquise diamond

This 0.73ct lab-grown marquise sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG651473399 or 651473399. Listed at 22 retailers as of November 4, 2026, with prices from £144 to £1,378, a £1,234 spread on the same certified stone. Do Amore Diamonds lists it at £1,378. Flawless clarity in sub-one-carat stones is rarely visible to the naked eye over VS1, so you are paying a meaningful premium for grade rather than appearance.
