This 1ct lab-grown marquise sits in the classic one-carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG447073861 or 447073861. Listed at 7 retailers as of October 29, 2026, with prices from €591 to €1,676, a €1,085 spread on the same certified stone. MOH London lists it at €1,676. 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.
