About this 1.53ct natural heart diamond

This 1.53ct natural heart sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI 320856183. Listed at 15 retailers as of November 5, 2026, with prices from $9,615 to $18,440, a $8,825 spread on the same certified stone. NZ Jewellers lists it at $18,440. 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.
