About this 1.51ct natural heart diamond

This 1.51ct natural heart sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 660478809. Listed at 15 retailers as of November 5, 2026, with prices from €5,357 to €10,305, a €4,949 spread on the same certified stone. NZ Jewellers lists it at €10,305. 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.
