About this 2.51ct lab-grown cushion diamond

This 2.51ct lab-grown cushion sits in the two to three carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG800618876 or 800618876. Listed at 18 retailers as of November 1, 2026, with prices from $476 to $4,040, a $3,564 spread on the same certified stone. Brilliant Earth lists it at $4,040. 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.
