Listed at 12 retailers as of October 29, 2026, with prices from HK$185,465 to HK$364,624, a HK$179,160 spread on the same certified stone. MOH London lists it at HK$364,624. 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.
