Listed at 4 retailers as of October 30, 2026, with prices from HK$52,720 to HK$188,870, a HK$136,150 spread on the same certified stone. Adiamor lists it at HK$188,870. 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.
