About this 0.81ct lab-grown radiant diamond

This 0.81ct 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 LG825632611 or 825632611. Listed at 17 retailers as of November 3, 2026, with prices from £264 to £1,175, a £911 spread on the same certified stone. MOH London lists it at £1,175. 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.
