This 15.1ct lab-grown cushion sits in the over five carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG778692474 or 778692474. Listed at 16 retailers as of November 1, 2026, with prices from £3,024 to £12,966, a £9,943 spread on the same certified stone. With Clarity lists it at £12,966. 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.
