About this 0.97ct lab-grown asscher diamond

This 0.97ct lab-grown asscher sits in the just-under-one-carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG818670252 or 818670252. Listed at 19 retailers as of October 27, 2026, with prices from £268 to £1,359, a £1,091 spread on the same certified stone. Brilliant Earth lists it at £1,359. 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.
