About this 0.7ct lab-grown cushion diamond

This 0.7ct lab-grown cushion sits in the half to three-quarter carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG840619785 or 840619785. Listed at 2 retailers as of November 4, 2026, with prices from £404 to £1,053, a £649 spread on the same certified stone. Taylor and Hart lists it at £1,053. 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.
