About this 0.75ct lab-grown cushion diamond

This 0.75ct lab-grown cushion sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG839620767 or 839620767. Listed at 18 retailers as of November 3, 2026, with prices from £255 to £1,080, a £825 spread on the same certified stone. Reve Diamonds lists it at £1,080. 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.
