About this 0.69ct lab-grown marquise diamond

This 0.69ct lab-grown marquise sits in the half to three-quarter carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG794623421 or 794623421. Listed at 11 retailers as of November 2, 2026, with prices from £222 to £1,976, a £1,754 spread on the same certified stone. Do Amore Diamonds lists it at £1,976. 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.
