About this 3.08ct lab-grown cushion diamond

This 3.08ct 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 LG818659077 or 818659077. Listed at 17 retailers as of October 29, 2026, with prices from $2,108 to $13,180, a $11,072 spread on the same certified stone. Brilliant Earth lists it at $13,180. 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.
