About this 0.55ct natural radiant diamond

This 0.55ct 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 7548177639. Listed at 4 retailers as of November 6, 2026, with prices from HK$4,115 to HK$5,251, a HK$1,136 spread on the same certified stone. Brilliant Earth lists it at HK$5,251. 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.
