About this 1.2ct lab-grown cushion diamond

This 1.2ct lab-grown cushion sits in the classic one-carat band, graded F colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG790644838 or 790644838. Listed at 13 retailers as of November 4, 2026, with prices from €918 to €3,356, a €2,438 spread on the same certified stone. Taylor and Hart lists it at €3,356. 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.
