About this 1.21ct natural heart diamond

This 1.21ct natural heart sits in the classic one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by HRD 260000071653. Listed at 5 retailers as of November 3, 2026, with prices from HK$17,070 to HK$36,428, a HK$19,358 spread on the same certified stone. NZ Jewellers lists it at HK$36,428. 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.
