Listed at 15 retailers as of October 30, 2026, with prices from HK$6,261 to HK$25,767, a HK$19,506 spread on the same certified stone. MOH London lists it at HK$25,767. 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.
