About this 1.23ct lab-grown oval diamond

This 1.23ct lab-grown oval sits in the classic one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG837650814 or 837650814. Listed at 4 retailers as of November 1, 2026, with a relatively tight 14% 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.
