About this 0.48ct lab-grown radiant diamond

This 0.48ct lab-grown radiant sits in the sub-half-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG645485148 or 645485148. Listed at 3 retailers as of October 29, 2026, with a relatively tight 0% 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.
