Listed at 7 retailers as of November 5, 2026, with prices from HK$3,080 to HK$8,102, a HK$5,022 spread on the same certified stone. MOH London lists it at HK$8,102. 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.
