This 10.03ct lab-grown cushion sits in the over five carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG848670123 or 848670123. Listed at 10 retailers as of October 30, 2026, with prices from £1,429 to £5,595, a £4,166 spread on the same certified stone. Taylor and Hart lists it at £5,595. 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.
