About this 1.03ct lab-grown round diamond

This 1.03ct lab-grown round sits in the classic one-carat band, graded J colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG840641807 or 840641807. Listed at 12 retailers as of October 29, 2026, with prices from £196 to £980, a £784 spread on the same certified stone. MOH London lists it at £980. 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.
