Listed at 21 retailers as of November 4, 2026, with prices from HK$1,577 to HK$12,160, a HK$10,583 spread on the same certified stone. Brilliant Earth lists it at HK$12,160. 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.
