This 1.51ct lab-grown marquise sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included) and certified by IGI LG781603850 or 781603850. Listed at 6 retailers as of November 1, 2026, with prices from €222 to €1,079, a €857 spread on the same certified stone. Frank Darling lists it at €1,079. 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.
