This 1.29ct lab-grown marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG801682733 or 801682733. Listed at 14 retailers as of October 30, 2026, with prices from €284 to €1,088, a €804 spread on the same certified stone. Brilliant Earth lists it at €1,088. 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.
