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 VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 782657022. Listed at 17 retailers as of November 4, 2026, with prices from HK$51,315 to HK$98,983, a HK$47,667 spread on the same certified stone. NZ Jewellers lists it at HK$98,983. 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.
