About this 5.03ct lab-grown round diamond

This 5.03ct lab-grown round sits in the over five carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG837644700 or 837644700. Listed at 8 retailers as of October 31, 2026, with a 281% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
