About this 1.7ct natural heart diamond

This 1.7ct natural heart sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 737519484. Listed at 9 retailers as of October 29, 2026, with prices from $10,261 to $18,591, a $8,331 spread on the same certified stone. NZ Jewellers lists it at $18,591. 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.
