This 3.08ct lab-grown radiant sits in the three to five carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG800684600 or 800684600. Listed at 14 retailers as of October 29, 2026, with prices from $1,830 to $12,960, a $11,130 spread on the same certified stone. Brilliant Earth lists it at $12,960. 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.
