This 1.28ct 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 LG851604790 or 851604790. Listed at 20 retailers as of November 1, 2026, with prices from €185 to €1,083, a €899 spread on the same certified stone. Reve Diamonds lists it at €1,083. 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.
