This 4.05ct lab-grown radiant sits in the three to five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG662415764 or 662415764. Listed at 23 retailers as of October 29, 2026, with prices from $2,131 to $13,433, a $11,302 spread on the same certified stone. Diamond Quarter lists it at $13,433. 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.
