This 4.05ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG833632333 or 833632333. Listed at 16 retailers as of October 27, 2026, with prices from £415 to £2,791, a £2,376 spread on the same certified stone. Brilliant Earth lists it at £2,791. 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.
