About this 0.8ct natural radiant diamond

This 0.8ct natural radiant sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6551839670. Listed at 3 retailers as of November 5, 2026, with prices from HK$19,531 to HK$23,324, a HK$3,793 spread on the same certified stone. Blue Nile lists it at HK$23,324. 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.
