About this 1.2ct natural heart diamond

This 1.2ct natural heart sits in the classic one-carat band, graded J 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 7536870829. Listed at 16 retailers as of November 5, 2026, with prices from HK$10,486 to HK$34,359, a HK$23,873 spread on the same certified stone. NZ Jewellers lists it at HK$34,359. 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.
