This 1.91ct lab-grown marquise sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG847671564 or 847671564. Listed at 6 retailers as of November 1, 2026, with prices from €445 to €1,114, a €670 spread on the same certified stone. Rare Carat lists it at €1,114. 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.
