About this 1.63ct natural heart diamond

This 1.63ct natural heart sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 835638860. Listed at 15 retailers as of November 5, 2026, with prices from HK$16,984 to HK$45,034, a HK$28,050 spread on the same certified stone. NZ Jewellers lists it at HK$45,034. 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.
