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 VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG689521505 or 689521505. Listed at 10 retailers as of October 24, 2026, with prices from £184 to £920, a £737 spread on the same certified stone. Reve Diamonds lists it at £920. 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.
