Listed at 15 retailers as of October 29, 2026, with prices from HK$2,887 to HK$14,079, a HK$11,192 spread on the same certified stone. MOH London lists it at HK$14,079. 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.
