About this 1.51ct natural heart diamond

This 1.51ct natural heart sits in the one-and-a-half to two carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 600359731. Listed at 13 retailers as of November 5, 2026, with prices from $13,841 to $25,440, a $11,599 spread on the same certified stone. NZ Jewellers lists it at $25,440. 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.
