About this 0.56ct lab-grown marquise diamond

This 0.56ct 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 LG798611957 or 798611957. Listed at 21 retailers as of November 3, 2026, with prices from £129 to £779, a £650 spread on the same certified stone. Reve Diamonds lists it at £779. 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.
