About this 4.24ct lab-grown cushion diamond

This 4.24ct lab-grown cushion sits in the three to five carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG768630665 or 768630665. Listed at 12 retailers as of October 30, 2026, with prices from $6,213 to $25,670, a $19,458 spread on the same certified stone. Taylor and Hart lists it at $25,670. 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.
