About this 0.81ct natural heart diamond

This 0.81ct natural heart sits in the just-under-one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1413611078. Listed at 9 retailers as of October 30, 2026, with prices from HK$21,702 to HK$41,726, a HK$20,023 spread on the same certified stone. NZ Jewellers lists it at HK$41,726. 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.
