About this 1.7ct natural heart diamond

This 1.7ct 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 very-good cut grade and certified by IGI 821674254. Listed at 24 retailers as of October 27, 2026, with prices from $8,501 to $16,452, a $7,951 spread on the same certified stone. NZ Jewellers lists it at $16,452. 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.
