This 12.1ct 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 LG589390525 or 589390525. Listed at 14 retailers as of October 31, 2026, with prices from €1,965 to €12,621, a €10,656 spread on the same certified stone. Brilliant Earth lists it at €12,621. 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.
