About this 0.97ct lab-grown marquise diamond

This 0.97ct lab-grown marquise sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG649496555 or 649496555. Listed at 22 retailers as of October 27, 2026, with prices from £273 to £2,418, a £2,145 spread on the same certified stone. Do Amore Diamonds lists it at £2,418. 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.
