Listed at 4 retailers as of November 4, 2026, with prices from HK$546,002 to HK$843,920, a HK$297,918 spread on the same certified stone. MOH London lists it at HK$843,920. 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.
