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 4, 2026, with prices from $623 to $2,768, a $2,146 spread on the same certified stone. Reve Diamonds lists it at $2,768. 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.
