This 1.03ct lab-grown round sits in the classic one-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG846647404 or 846647404. Listed at 9 retailers as of October 26, 2026, with prices from €228 to €792, a €564 spread on the same certified stone. MOH London lists it at €792. 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.
