About this 1.04ct lab-grown radiant diamond

This 1.04ct lab-grown radiant sits in the classic one-carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG603339941 or 603339941. Listed at 2 retailers as of November 2, 2026, with prices from £309 to £359, a £50 spread on the same certified stone. MD Diamonds and Jewellers lists it at £359. 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.
