About this 1.1ct lab-grown cushion diamond

This 1.1ct lab-grown cushion sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG839612176 or 839612176. Listed at 3 retailers as of November 1, 2026, with prices from €256 to €1,422, a €1,166 spread on the same certified stone. Rare Carat lists it at €1,422. 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.
