This 1.7ct lab-grown marquise sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG789633233 or 789633233. Listed at 3 retailers as of October 31, 2026, with prices from €946 to €1,352, a €406 spread on the same certified stone. Brilliant Earth lists it at €1,352. 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.
