About this 0.8ct lab-grown radiant diamond

This 0.8ct lab-grown radiant sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG818658721 or 818658721. Listed at 16 retailers as of November 3, 2026, with prices from £261 to £1,162, a £901 spread on the same certified stone. MOH London lists it at £1,162. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
