About this 0.54ct lab-grown marquise diamond

This 0.54ct 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 LG791653445 or 791653445. Listed at 28 retailers as of November 4, 2026, with prices from £159 to £1,519, a £1,360 spread on the same certified stone. Do Amore Diamonds lists it at £1,519. 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.
