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 17 retailers as of November 1, 2026, with prices from €424 to €3,602, a €3,178 spread on the same certified stone. Brilliant Earth lists it at €3,602. 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.
