Listed at 8 retailers as of November 1, 2026, with prices from HK$2,735 to HK$7,754, a HK$5,019 spread on the same certified stone. MOH London lists it at HK$7,754. 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.
