About this 1.2ct natural heart diamond

This 1.2ct natural heart sits in the classic one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 800626000. Listed at 13 retailers as of November 5, 2026, with prices from HK$16,796 to HK$38,866, a HK$22,070 spread on the same certified stone. NZ Jewellers lists it at HK$38,866. 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.
