Listed at 9 retailers as of October 29, 2026, with prices from HK$8,771 to HK$38,020, a HK$29,249 spread on the same certified stone. Blue Nile lists it at HK$38,020. 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.
