Listed at 24 retailers as of November 4, 2026, with prices from HK$2,487 to HK$17,261, a HK$14,774 spread on the same certified stone. Brilliant Earth lists it at HK$17,261. 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.
