About this 0.79ct lab-grown radiant diamond

This 0.79ct lab-grown radiant 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 LG818658783 or 818658783. Listed at 18 retailers as of November 3, 2026, with prices from £182 to £932, a £750 spread on the same certified stone. Reve Diamonds lists it at £932. 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.
