This 1.87ct lab-grown cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG833637874 or 833637874. Listed at 19 retailers as of October 31, 2026, with prices from €1,293 to €5,857, a €4,563 spread on the same certified stone. Riddles Jewelry lists it at €5,857. 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.
