About this 0.79ct lab-grown marquise diamond
This 0.79ct lab-grown marquise sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG816654969 or 816654969. Listed at 28 retailers as of November 4, 2026, with prices from £203 to £1,615, a £1,412 spread on the same certified stone. Do Amore Diamonds lists it at £1,615. 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.
