About this 1.2ct lab-grown round diamond

This 1.2ct lab-grown round sits in the classic one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG547268208 or 547268208. Listed at 3 retailers as of November 6, 2026, with a relatively tight 12% 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.
