About this 1.02ct lab-grown radiant diamond

This 1.02ct lab-grown radiant sits in the classic one-carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG648415807 or 648415807. Listed at 5 retailers as of November 1, 2026, with prices from £194 to £813, a £618 spread on the same certified stone. MOH London lists it at £813. 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.
