This 1.03ct lab-grown round sits in the classic one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG846647387 or 846647387. Listed at 8 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.
