This 2.91ct lab-grown radiant sits in the two to three carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG622492935 or 622492935. Listed at 25 retailers as of October 29, 2026, with prices from $1,728 to $15,047, a $13,319 spread on the same certified stone. Brilliant Earth lists it at $15,047. 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.
