About this 5.48ct lab-grown cushion diamond

This 5.48ct lab-grown cushion sits in the over five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG761557981 or 761557981. Listed at 12 retailers as of October 29, 2026, with prices from $4,586 to $16,881, a $12,295 spread on the same certified stone. Taylor and Hart lists it at $16,881. 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.
