About this 0.81ct natural radiant diamond

This 0.81ct natural radiant 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 1558508791. Listed at 8 retailers as of October 28, 2026, with prices from HK$9,454 to HK$13,181, a HK$3,727 spread on the same certified stone. Jared lists it at HK$13,181. 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.
