About this 1.2ct natural heart diamond

This 1.2ct natural heart sits in the classic one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 743513531. Listed at 14 retailers as of November 5, 2026, with prices from HK$14,170 to HK$38,278, a HK$24,108 spread on the same certified stone. NZ Jewellers lists it at HK$38,278. 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.
