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 SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5436221017. Listed at 16 retailers as of October 30, 2026, with prices from HK$4,857 to HK$18,211, a HK$13,354 spread on the same certified stone. NZ Jewellers lists it at HK$18,211. 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.
