Listed at 21 retailers as of October 29, 2026, with prices from HK$926 to HK$9,595, a HK$8,670 spread on the same certified stone. MOH London lists it at HK$9,595. 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.
