About this 2.59ct lab-grown cushion diamond

This 2.59ct lab-grown cushion sits in the two to three carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG728517095 or 728517095. Listed at 18 retailers as of October 28, 2026, with prices from $1,685 to $8,720, a $7,034 spread on the same certified stone. Brilliant Earth lists it at $8,720. 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.
