Listed at 19 retailers as of November 4, 2026, with prices from HK$1,922 to HK$14,514, a HK$12,592 spread on the same certified stone. Brilliant Earth lists it at HK$14,514. 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.
