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 LG792643085 or 792643085. Listed at 11 retailers as of October 29, 2026, with prices from £621 to £2,540, a £1,919 spread on the same certified stone. MOH London lists it at £2,540. 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.
