About this 4.1ct lab-grown cushion diamond

This 4.1ct 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 LG768628655 or 768628655. Listed at 13 retailers as of October 30, 2026, with prices from $4,234 to $17,435, a $13,201 spread on the same certified stone. Taylor and Hart lists it at $17,435. 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.
