About this 1.02ct lab-grown radiant diamond

This 1.02ct lab-grown radiant sits in the classic one-carat band, graded H colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG621490379 or 621490379. Listed at 2 retailers as of October 29, 2026, with a relatively tight 5% 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.
