About this 2.55ct lab-grown cushion diamond

This 2.55ct 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 LG722561902 or 722561902. Listed at 18 retailers as of October 29, 2026, with prices from $1,688 to $8,725, a $7,037 spread on the same certified stone. Brilliant Earth lists it at $8,725. 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.
