Listed at 7 retailers as of November 4, 2026, with prices from HK$6,449 to HK$20,028, a HK$13,579 spread on the same certified stone. MOH London lists it at HK$20,028. 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.
