About this 1.09ct lab-grown radiant diamond

This 1.09ct lab-grown radiant sits in the classic one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG651425162 or 651425162. Listed at 19 retailers as of October 30, 2026, with prices from £128 to £825, a £697 spread on the same certified stone. Reve Diamonds lists it at £825. 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.
