About this 1.59ct natural heart diamond

This 1.59ct natural heart sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 704547061. Listed at 13 retailers as of October 30, 2026, with prices from $10,535 to $20,387, a $9,851 spread on the same certified stone. NZ Jewellers lists it at $20,387. 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.
