About this 0.83ct lab-grown marquise diamond

This 0.83ct 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 LG733557849 or 733557849. Listed at 15 retailers as of November 4, 2026, with prices from £141 to £2,089, a £1,948 spread on the same certified stone. Do Amore Diamonds lists it at £2,089. 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.
