About this 0.5ct natural radiant diamond

This 0.5ct natural radiant sits in the half to three-quarter carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5221308644. Listed at 7 retailers as of October 30, 2026, with prices from HK$4,676 to HK$14,664, a HK$9,988 spread on the same certified stone. NZ Jewellers lists it at HK$14,664. 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.
