Listed at 12 retailers as of November 6, 2026, with prices from HK$1,646 to HK$8,480, a HK$6,835 spread on the same certified stone. MOH London lists it at HK$8,480. 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.
