About this 3.02ct lab-grown cushion diamond

This 3.02ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG840627982 or 840627982. Listed at 11 retailers as of November 6, 2026, with prices from £534 to £3,525, a £2,991 spread on the same certified stone. Mervis Diamond Importers lists it at £3,525. 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.
