About this 2.03ct lab-grown cushion diamond

This 2.03ct lab-grown cushion sits in the two to three carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG837624413 or 837624413. Listed at 12 retailers as of November 6, 2026, with prices from £189 to £1,136, a £947 spread on the same certified stone. Brilliant Earth lists it at £1,136. 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.
