About this 1.21ct natural heart diamond

This 1.21ct natural heart sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1537737014. Listed at 9 retailers as of November 5, 2026, with prices from HK$22,290 to HK$46,437, a HK$24,147 spread on the same certified stone. NZ Jewellers lists it at HK$46,437. 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.
