About this 0.9ct lab-grown cushion diamond

This 0.9ct 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 LG839698294 or 839698294. Listed at 10 retailers as of November 1, 2026, with prices from £522 to £2,355, a £1,832 spread on the same certified stone. MOH London lists it at £2,355. 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.
