This 0.42ct lab-grown marquise sits in the sub-half-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG756513927 or 756513927. Listed at 11 retailers as of November 1, 2026, with prices from €205 to €1,204, a €999 spread on the same certified stone. Kay Jewelers lists it at €1,204. 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.
