This 3.2ct lab-grown radiant sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG732516557 or 732516557. Listed at 16 retailers as of October 29, 2026, with prices from $1,402 to $17,131, a $15,729 spread on the same certified stone. Brilliant Earth lists it at $17,131. 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.
