This 0.82ct lab-grown radiant sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG818661990 or 818661990. Listed at 19 retailers as of November 3, 2026, with prices from £267 to £1,188, a £922 spread on the same certified stone. MOH London lists it at £1,188. 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.
