Listed at 7 retailers as of November 4, 2026, with prices from HK$2,487 to HK$6,765, a HK$4,278 spread on the same certified stone. MOH London lists it at HK$6,765. 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.
