This 1.09ct lab-grown oval sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG850690105 or 850690105. Listed at 7 retailers as of October 29, 2026, with prices from €206 to €843, a €637 spread on the same certified stone. MOH London lists it at €843. 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.
