About this 1.07ct natural heart diamond

This 1.07ct natural heart sits in the classic one-carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 181509633. Listed at 6 retailers as of October 30, 2026, with prices from HK$16,979 to HK$35,488, a HK$18,509 spread on the same certified stone. NZ Jewellers lists it at HK$35,488. 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.
