About this 0.81ct natural radiant diamond

This 0.81ct natural radiant sits in the just-under-one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2437187050. Listed at 23 retailers as of October 30, 2026, with prices from HK$6,628 to HK$21,687, a HK$15,058 spread on the same certified stone. NZ Jewellers lists it at HK$21,687. 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.
