Listed at 3 retailers as of November 6, 2026, with prices from HK$1,325 to HK$5,721, a HK$4,397 spread on the same certified stone. Brilliant Earth lists it at HK$5,721. 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.
