This 1.23ct lab-grown marquise sits in the classic one-carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG825655360 or 825655360. Listed at 16 retailers as of November 2, 2026, with prices from €207 to €921, a €714 spread on the same certified stone. MOH London lists it at €921. 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.
