This 0.99ct lab-grown cushion sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG667417967 or 667417967. Listed at 14 retailers as of October 29, 2026, with prices from €311 to €1,772, a €1,462 spread on the same certified stone. Brilliant Earth lists it at €1,772. 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.
