About this 1.2ct natural heart diamond

This 1.2ct natural heart sits in the classic one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2241072436. Listed at 12 retailers as of November 5, 2026, with prices from HK$11,733 to HK$33,450, a HK$21,717 spread on the same certified stone. NZ Jewellers lists it at HK$33,450. 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.
