Listed at 22 retailers as of October 30, 2026, with prices from HK$1,757 to HK$17,574, a HK$15,817 spread on the same certified stone. Brilliant Earth lists it at HK$17,574. 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.
