This 12.03ct 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 LG750575909 or 750575909. Listed at 6 retailers as of November 1, 2026, with prices from £2,595 to £13,434, a £10,839 spread on the same certified stone. Do Amore Diamonds lists it at £13,434. 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.
