About this 0.98ct lab-grown cushion diamond

This 0.98ct lab-grown cushion sits in the just-under-one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG623481118 or 623481118. Listed at 14 retailers as of November 1, 2026, with a 170% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
