This 3.07ct lab-grown radiant sits in the three to five carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG629432491 or 629432491. Listed at 8 retailers as of November 4, 2026, with prices from £1,445 to £5,003, a £3,558 spread on the same certified stone. Taylor and Hart lists it at £5,003. 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.
