About this 0.98ct lab-grown radiant diamond

This 0.98ct lab-grown radiant sits in the just-under-one-carat band, graded F colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG790608018 or 790608018. Listed at 12 retailers as of November 4, 2026, with prices from £242 to £2,148, a £1,906 spread on the same certified stone. Do Amore Diamonds lists it at £2,148. 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.
