Listed at 11 retailers as of November 1, 2026, with prices from HK$3,546 to HK$17,497, a HK$13,950 spread on the same certified stone. Brilliant Earth lists it at HK$17,497. 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.
