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 SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5376670316. Listed at 17 retailers as of November 5, 2026, with prices from HK$18,410 to HK$43,482, a HK$25,072 spread on the same certified stone. NZ Jewellers lists it at HK$43,482. 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.
