About this 1.13ct lab-grown radiant diamond

This 1.13ct lab-grown radiant sits in the classic one-carat band, graded I colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG681504531 or 681504531. Listed at 15 retailers as of October 26, 2026, with prices from £109 to £639, a £530 spread on the same certified stone. MOH London lists it at £639. 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.
