This 2.58ct lab-grown cushion sits in the two to three carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG715581426 or 715581426. Listed at 13 retailers as of October 30, 2026, with prices from £676 to £2,993, a £2,317 spread on the same certified stone. Brilliant Earth lists it at £2,993. 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.
