About this 1.02ct lab-grown radiant diamond

This 1.02ct lab-grown radiant sits in the classic one-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by IGI LG581333985 or 581333985. Listed at 15 retailers as of November 5, 2026, with prices from £144 to £753, a £609 spread on the same certified stone. MOH London lists it at £753. 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.
