About this 0.98ct lab-grown cushion diamond

This 0.98ct lab-grown cushion sits in the just-under-one-carat band, graded F colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG836620951 or 836620951. Listed at 12 retailers as of November 4, 2026, with prices from £409 to £1,334, a £925 spread on the same certified stone. Taylor and Hart lists it at £1,334. 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.
