About this 4.07ct lab-grown cushion diamond

This 4.07ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG678556777 or 678556777. Listed at 17 retailers as of October 31, 2026, with prices from €2,667 to €8,806, a €6,139 spread on the same certified stone. Taylor and Hart lists it at €8,806. 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.
