About this 2.56ct lab-grown cushion diamond

This 2.56ct lab-grown cushion sits in the two to three carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG825658596 or 825658596. Listed at 18 retailers as of October 29, 2026, with prices from $2,188 to $10,930, a $8,742 spread on the same certified stone. Brilliant Earth lists it at $10,930. 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.
