This 1.63ct lab-grown cushion sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG613350559 or 613350559. Listed at 17 retailers as of October 29, 2026, with prices from €358 to €1,781, a €1,424 spread on the same certified stone. Brilliant Earth lists it at €1,781. 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.
