This 2.09ct lab-grown cushion sits in the two to three carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG761515275 or 761515275. Listed at 11 retailers as of November 6, 2026, with prices from €250 to €1,558, a €1,309 spread on the same certified stone. Brilliant Earth lists it at €1,558. 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.
