This 1.01ct lab-grown round sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG688518446 or 688518446. Listed at 17 retailers as of October 30, 2026, with prices from €152 to €763, a €611 spread on the same certified stone. MOH London lists it at €763. 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.
