This 1.34ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI LG801621870 or 801621870. Listed at 20 retailers as of October 30, 2026, with prices from £263 to £2,060, a £1,796 spread on the same certified stone. Brilliant Earth lists it at £2,060. 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.
