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 6541513711. Listed at 5 retailers as of November 4, 2026, with prices from HK$5,673 to HK$7,046, a HK$1,373 spread on the same certified stone. Blue Nile lists it at HK$7,046. 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.
