About this 0.51ct natural radiant diamond

This 0.51ct natural radiant sits in the half to three-quarter carat band, graded E 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 6545447302. Listed at 4 retailers as of November 4, 2026, with prices from HK$5,790 to HK$9,067, a HK$3,277 spread on the same certified stone. GemTrove lists it at HK$9,067. 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.
