This 2.9ct lab-grown radiant sits in the two to three carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG774610050 or 774610050. Listed at 23 retailers as of October 28, 2026, with prices from £761 to £5,539, a £4,778 spread on the same certified stone. Brilliant Earth lists it at £5,539. 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.
