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 27, 2026, with prices from $2,571 to $18,139, a $15,568 spread on the same certified stone. Brilliant Earth lists it at $18,139. 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.
