Listed at 10 retailers as of November 3, 2026, with prices from HK$4,307 to HK$13,521, a HK$9,214 spread on the same certified stone. MOH London lists it at HK$13,521. 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.
