About this 0.49ct lab-grown marquise diamond

This 0.49ct lab-grown marquise sits in the sub-half-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG786619126 or 786619126. Listed at 16 retailers as of October 30, 2026, with prices from £126 to £819, a £693 spread on the same certified stone. Flawless Fine Jewelry lists it at £819. 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.
