About this 0.91ct lab-grown asscher diamond

This 0.91ct lab-grown asscher 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 LG804673093 or 804673093. Listed at 20 retailers as of November 2, 2026, with prices from £163 to £1,104, a £940 spread on the same certified stone. Brilliant Earth lists it at £1,104. 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.
