This 3.51ct lab-grown radiant sits in the three to five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG673412609 or 673412609. Listed at 23 retailers as of October 30, 2026, with prices from $1,627 to $11,212, a $9,584 spread on the same certified stone. Brilliant Earth lists it at $11,212. 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.
