About this 2.5ct lab-grown cushion diamond

This 2.5ct lab-grown cushion sits in the two to three carat band, graded G colour (near-colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG607344944 or 607344944. Listed at 18 retailers as of October 31, 2026, with prices from $1,510 to $5,498, a $3,988 spread on the same certified stone. Taylor and Hart lists it at $5,498. 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.
