About this 0.5ct natural heart diamond

This 0.5ct natural heart sits in the half to three-quarter carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6392146832. Listed at 14 retailers as of November 5, 2026, with prices from HK$3,605 to HK$13,418, a HK$9,812 spread on the same certified stone. NZ Jewellers lists it at HK$13,418. 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.
