About this 1.03ct lab-grown radiant diamond

This 1.03ct lab-grown radiant sits in the classic one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG803628046 or 803628046. Listed at 16 retailers as of November 4, 2026, with prices from €130 to €750, a €620 spread on the same certified stone. MOH London lists it at €750. 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.
