About this 1.2ct natural heart diamond

This 1.2ct natural heart sits in the classic one-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 6243054497. Listed at 10 retailers as of November 5, 2026, with prices from HK$13,135 to HK$37,471, a HK$24,335 spread on the same certified stone. NZ Jewellers lists it at HK$37,471. 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.
