About this 1.22ct lab-grown radiant diamond
This 1.22ct lab-grown radiant sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI. Listed at 7 retailers as of November 3, 2026, with a relatively tight 21% spread, which is unusual at this carat range and suggests competitive pricing across the listings. 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.
