This 3.04ct 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 LG835690251 or 835690251. Listed at 17 retailers as of October 25, 2026, with prices from £407 to £3,314, a £2,906 spread on the same certified stone. Brilliant Earth lists it at £3,314. 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.
