About this 1.98ct lab-grown cushion diamond

This 1.98ct lab-grown cushion sits in the one-and-a-half to two carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG805623137 or 805623137. Listed at 12 retailers as of November 6, 2026, with prices from £256 to £1,584, a £1,328 spread on the same certified stone. Brilliant Earth lists it at £1,584. 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.
