Listed at 18 retailers as of October 29, 2026, with prices from HK$2,205 to HK$11,021, a HK$8,816 spread on the same certified stone. MOH London lists it at HK$11,021. 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.
