About this 0.82ct lab-grown asscher diamond

This 0.82ct 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 LG653441507 or 653441507. Listed at 2 retailers as of October 31, 2026, with prices from £148 to £796, a £648 spread on the same certified stone. Diamond Quarter lists it at £796. 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.
