This 3.09ct lab-grown cushion sits in the three to five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG731543041 or 731543041. Listed at 15 retailers as of November 3, 2026, with prices from £984 to £3,786, a £2,802 spread on the same certified stone. Taylor and Hart lists it at £3,786. 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.
