This 0.99ct lab-grown round sits in the just-under-one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG727519412 or 727519412. Listed at 13 retailers as of October 26, 2026, with prices from €103 to €1,102, a €999 spread on the same certified stone. MOH London lists it at €1,102. 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.
