This 3.03ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG843652298 or 843652298. Listed at 18 retailers as of October 24, 2026, with prices from £491 to £3,680, a £3,189 spread on the same certified stone. Brilliant Earth lists it at £3,680. 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.
