Listed at 11 retailers as of October 29, 2026, with prices from HK$2,150 to HK$10,751, a HK$8,601 spread on the same certified stone. MOH London lists it at HK$10,751. 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.
