About this 1.16ct lab-grown radiant diamond

This 1.16ct 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 LG669443991 or 669443991. Listed at 13 retailers as of October 26, 2026, with prices from £142 to £825, a £683 spread on the same certified stone. MOH London 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.
