About this 1.7ct natural heart diamond

This 1.7ct natural heart sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 700528984. Listed at 12 retailers as of November 4, 2026, with prices from HK$23,348 to HK$45,825, a HK$22,478 spread on the same certified stone. NZ Jewellers lists it at HK$45,825. 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.
