About this 0.5ct natural emerald diamond

This 0.5ct natural emerald sits in the half to three-quarter carat band, graded K colour (faint-tinted) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 815676181. Listed at 13 retailers as of November 4, 2026, with a 75% 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.
