About this 0.82ct lab-grown round diamond

This 0.82ct lab-grown round sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG817670968 or 817670968. Listed at 20 retailers as of October 28, 2026, with prices from £140 to £816, a £676 spread on the same certified stone. Reve Diamonds lists it at £816. 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.
