About this 1.81ct natural heart diamond

This 1.81ct natural heart sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 632436405. Listed at 11 retailers as of November 2, 2026, with a 60% 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.
