About this 1.51ct natural heart diamond

This 1.51ct 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 440097543. Listed at 14 retailers as of November 5, 2026, with prices from HK$26,639 to HK$52,746, a HK$26,106 spread on the same certified stone. NZ Jewellers lists it at HK$52,746. 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.
