About this 0.51ct natural radiant diamond

This 0.51ct natural radiant sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2556234497. Listed at 16 retailers as of October 30, 2026, with prices from HK$5,423 to HK$22,903, a HK$17,480 spread on the same certified stone. NZ Jewellers lists it at HK$22,903. 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.
