Listed at 13 retailers as of October 31, 2026, with prices from HK$27,107 to HK$117,003, a HK$89,896 spread on the same certified stone. With Clarity lists it at HK$117,003. 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.
