This 3.1ct 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 LG753503909 or 753503909. Listed at 25 retailers as of October 27, 2026, with prices from $1,631 to $14,675, a $13,044 spread on the same certified stone. Brilliant Earth lists it at $14,675. 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.
