About this 0.56ct natural radiant diamond

This 0.56ct 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 2566530667. Listed at 3 retailers as of November 4, 2026, with prices from HK$5,126 to HK$6,160, a HK$1,035 spread on the same certified stone. Brilliance lists it at HK$6,160. 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.
