About this 1.57ct natural heart diamond

This 1.57ct 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 801638160. Listed at 17 retailers as of November 4, 2026, with prices from €4,562 to €8,748, a €4,186 spread on the same certified stone. NZ Jewellers lists it at €8,748. 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.
