Listed at 16 retailers as of November 1, 2026, with prices from HK$202,435 to HK$383,715, a HK$181,280 spread on the same certified stone. MOH London lists it at HK$383,715. 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.
