About this 0.74ct lab-grown marquise diamond

This 0.74ct 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 LG845658725 or 845658725. Listed at 7 retailers as of November 4, 2026, with prices from £265 to £961, a £696 spread on the same certified stone. MOH London lists it at £961. 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.
