About this 0.5ct natural radiant diamond

This 0.5ct natural radiant sits in the half to three-quarter carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7428519737. Listed at 18 retailers as of October 27, 2026, with prices from HK$4,720 to HK$17,678, a HK$12,958 spread on the same certified stone. NZ Jewellers lists it at HK$17,678. 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.
