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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 5546512528. Listed at 6 retailers as of October 26, 2026, with prices from HK$5,218 to HK$10,194, a HK$4,976 spread on the same certified stone. MOH London lists it at HK$10,194. 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.
