About this 0.89ct lab-grown marquise diamond

This 0.89ct 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 LG823646408 or 823646408. Listed at 8 retailers as of November 4, 2026, with prices from £213 to £1,504, a £1,290 spread on the same certified stone. Do Amore Diamonds lists it at £1,504. 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.
