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 LG803617331 or 803617331. Listed at 21 retailers as of November 4, 2026, with prices from £149 to £886, a £737 spread on the same certified stone. Reve Diamonds lists it at £886. 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.
