This 1.26ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG799688944 or 799688944. Listed at 4 retailers as of October 30, 2026, with prices from £520 to £963, a £443 spread on the same certified stone. Jared lists it at £963. 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.
