This 3.05ct lab-grown radiant sits in the three to five carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG742530306 or 742530306. Listed at 25 retailers as of November 4, 2026, with prices from $776 to $5,690, a $4,914 spread on the same certified stone. Brilliant Earth lists it at $5,690. 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.
