About this 1.51ct natural heart diamond

This 1.51ct 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 738527953. Listed at 7 retailers as of November 2, 2026, with prices from €2,328 to €5,395, a €3,067 spread on the same certified stone. NZ Jewellers lists it at €5,395. 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.
