About this 1.01ct lab-grown radiant diamond

This 1.01ct lab-grown radiant sits in the classic one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included) and certified by IGI LG612345356 or 612345356. Listed at 2 retailers as of November 5, 2026, with a relatively tight 15% 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.
