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 IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG836619851 or 836619851. Listed at 15 retailers as of November 3, 2026, with prices from £271 to £1,230, a £959 spread on the same certified stone. Brilliant Earth lists it at £1,230. 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.
