This 4.02ct lab-grown cushion sits in the three to five carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG618484876 or 618484876. Listed at 15 retailers as of October 26, 2026, with prices from £638 to £2,511, a £1,873 spread on the same certified stone. MOH London lists it at £2,511. 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.
