This 1.01ct lab-grown radiant sits in the classic one-carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG375940239 or 375940239. Listed at 8 retailers as of October 31, 2026, with prices from €537 to €2,072, a €1,535 spread on the same certified stone. NZ Jewellers lists it at €2,072. 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.
