This 1.08ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI LG842621699 or 842621699. Listed at 2 retailers as of October 30, 2026, with prices from £1,179 to £1,389, a £210 spread on the same certified stone. Taylor and Hart lists it at £1,389. 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.
