About this 1.03ct lab-grown heart diamond

This 1.03ct lab-grown heart sits in the classic one-carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG851636944 or 851636944. Listed at 3 retailers as of November 2, 2026, with a relatively tight 8% 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.
