About this 4.4ct lab-grown radiant diamond

This 4.4ct lab-grown radiant sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI. Listed at 7 retailers as of November 1, 2026, with a relatively tight 20% 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.
