Listed at 12 retailers as of October 29, 2026, with prices from HK$12,923 to HK$69,362, a HK$56,439 spread on the same certified stone. Brilliant Earth lists it at HK$69,362. 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.
