This 2.05ct lab-grown radiant sits in the two to three carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG635426495 or 635426495. Listed at 22 retailers as of November 2, 2026, with prices from £554 to £3,964, a £3,410 spread on the same certified stone. Brilliant Earth lists it at £3,964. 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.
