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 LG734516207 or 734516207. Listed at 16 retailers as of October 27, 2026, with prices from $2,493 to $9,070, a $6,577 spread on the same certified stone. Taylor and Hart lists it at $9,070. 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.
