Listed at 5 retailers as of November 1, 2026, with prices from HK$15,715 to HK$46,502, a HK$30,787 spread on the same certified stone. MOH London lists it at HK$46,502. 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.
