This 1.71ct lab-grown cushion sits in the one-and-a-half to two carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG845699641 or 845699641. Listed at 11 retailers as of October 28, 2026, with prices from €521 to €2,424, a €1,902 spread on the same certified stone. MOH London lists it at €2,424. 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.
