About this 3.17ct lab-grown cushion diamond

This 3.17ct lab-grown cushion sits in the three to five carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG770626755 or 770626755. Listed at 7 retailers as of November 1, 2026, with prices from €1,965 to €5,111, a €3,146 spread on the same certified stone. Rare Carat lists it at €5,111. 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.
