About this 0.7ct lab-grown marquise diamond

This 0.7ct 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 LG823695305 or 823695305. Listed at 20 retailers as of November 4, 2026, with prices from £357 to £1,624, a £1,267 spread on the same certified stone. MOH London lists it at £1,624. 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.
