About this 1ct lab-grown radiant diamond

This 1ct 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 LG640456855 or 640456855. Listed at 2 retailers as of October 29, 2026, with prices from €360 to €415, a €55 spread on the same certified stone. MD Diamonds and Jewellers lists it at €415. 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.
