Listed at 9 retailers as of November 1, 2026, with prices from HK$2,722 to HK$12,076, a HK$9,354 spread on the same certified stone. MOH London lists it at HK$12,076. 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.
