This 2.91ct lab-grown radiant sits in the two to three carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG594325625 or 594325625. Listed at 23 retailers as of October 29, 2026, with prices from £846 to £7,930, a £7,084 spread on the same certified stone. Brilliant Earth lists it at £7,930. 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.
