This 1.81ct lab-grown round sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG754510404 or 754510404. Listed at 15 retailers as of November 1, 2026, with prices from €191 to €972, a €781 spread on the same certified stone. Brilliant Earth lists it at €972. 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.
