This 4.03ct 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 LG768660863 or 768660863. Listed at 19 retailers as of October 29, 2026, with prices from $2,712 to $19,846, a $17,134 spread on the same certified stone. Brilliant Earth lists it at $19,846. 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.
