About this 0.98ct lab-grown cushion diamond

This 0.98ct lab-grown cushion sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG749509390 or 749509390. Listed at 11 retailers as of November 3, 2026, with prices from £373 to £2,667, a £2,293 spread on the same certified stone. Do Amore Diamonds lists it at £2,667. 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.
