About this 1.21ct lab-grown radiant diamond

This 1.21ct lab-grown radiant sits in the classic one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG799676982 or 799676982. Listed at 22 retailers as of October 31, 2026, with prices from $480 to $4,016, a $3,536 spread on the same certified stone. Brilliant Earth lists it at $4,016. 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.
