About this 10.03ct lab-grown radiant diamond

This 10.03ct lab-grown radiant sits in the over five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG680565510 or 680565510. Listed at 16 retailers as of October 31, 2026, with prices from €1,697 to €6,169, a €4,472 spread on the same certified stone. Taylor and Hart lists it at €6,169. 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.
