About this 3.09ct lab-grown cushion diamond

This 3.09ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG770626758 or 770626758. Listed at 7 retailers as of October 30, 2026, with prices from €2,065 to €5,149, a €3,083 spread on the same certified stone. Taylor and Hart lists it at €5,149. 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.
