About this 1.21ct natural heart diamond

This 1.21ct natural heart sits in the classic one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1469667794. Listed at 18 retailers as of November 5, 2026, with prices from HK$23,771 to HK$55,426, a HK$31,655 spread on the same certified stone. NZ Jewellers lists it at HK$55,426. 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.
