This 10.11ct lab-grown cushion sits in the over five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG821653125 or 821653125. Listed at 4 retailers as of October 30, 2026, with prices from £6,504 to £9,344, a £2,840 spread on the same certified stone. Zales lists it at £9,344. 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.
