This 3.08ct 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 LG836626618 or 836626618. Listed at 17 retailers as of October 31, 2026, with prices from £382 to £2,052, a £1,670 spread on the same certified stone. Brilliant Earth lists it at £2,052. 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.
