About this 2.5ct lab-grown cushion diamond

This 2.5ct lab-grown cushion sits in the two to three carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG800618153 or 800618153. Listed at 15 retailers as of October 30, 2026, with prices from £402 to £2,403, a £2,002 spread on the same certified stone. Brilliant Earth lists it at £2,403. 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.
