Listed at 21 retailers as of October 31, 2026, with prices from HK$63,487 to HK$290,208, a HK$226,720 spread on the same certified stone. Frank Darling lists it at HK$290,208. 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.
