About this 0.85ct lab-grown cushion diamond

This 0.85ct lab-grown cushion sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG663402007 or 663402007. Listed at 9 retailers as of November 1, 2026, with prices from €398 to €1,763, a €1,365 spread on the same certified stone. MOH London lists it at €1,763. 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.
