About this 1.3ct natural heart diamond

This 1.3ct natural heart sits in the one-and-a-quarter to one-and-a-half carat band, graded I 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 6551629611. Listed at 5 retailers as of November 5, 2026, with prices from HK$20,315 to HK$42,463, a HK$22,148 spread on the same certified stone. NZ Jewellers lists it at HK$42,463. 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.
