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 3, 2026, with prices from $12,426 to $21,640, a $9,214 spread on the same certified stone. NZ Jewellers lists it at $21,640. 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.
