About this 0.97ct lab-grown cushion diamond

This 0.97ct 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 LG818657657 or 818657657. Listed at 13 retailers as of November 3, 2026, with prices from £286 to £1,241, a £955 spread on the same certified stone. MOH London lists it at £1,241. 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.
