This 1.21ct lab-grown radiant sits in the classic one-carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG593372671 or 593372671. Listed at 6 retailers as of October 26, 2026, with prices from €273 to €981, a €708 spread on the same certified stone. MOH London lists it at €981. 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.
