About this 2.03ct lab-grown cushion diamond

This 2.03ct lab-grown cushion sits in the two to three carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG389999566 or 389999566. Listed at 7 retailers as of October 31, 2026, with prices from £253 to £776, a £523 spread on the same certified stone. Frank Darling lists it at £776. 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.
