About this 1.09ct lab-grown radiant diamond

This 1.09ct lab-grown radiant sits in the classic one-carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG844602870 or 844602870. Listed at 10 retailers as of November 6, 2026, with prices from $226 to $1,540, a $1,314 spread on the same certified stone. Brilliant Earth lists it at $1,540. 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.
