About this 0.99ct lab-grown cushion diamond

This 0.99ct lab-grown cushion sits in the just-under-one-carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG646486634 or 646486634. Listed at 3 retailers as of October 28, 2026, with a relatively tight 2% 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.
