This 10.2ct lab-grown heart sits in the over five carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG600342446 or 600342446. Listed at 3 retailers as of October 30, 2026, with prices from €1,582 to €4,643, a €3,061 spread on the same certified stone. Adiamor lists it at €4,643. 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.
