Listed at 18 retailers as of October 29, 2026, with prices from HK$10,898 to HK$96,267, a HK$85,369 spread on the same certified stone. Brilliant Earth lists it at HK$96,267. 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.
