This 1.24ct lab-grown marquise sits in the classic one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG844638668 or 844638668. Listed at 6 retailers as of October 29, 2026, with prices from €390 to €1,060, a €670 spread on the same certified stone. MOH London lists it at €1,060. 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.
