About this 1ct lab-grown radiant diamond

This 1ct lab-grown radiant sits in the classic one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included) and certified by IGI LG604384770 or 604384770. Listed at 2 retailers as of October 29, 2026, with a relatively tight 10% 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.
