Listed at 12 retailers as of October 30, 2026, with prices from HK$11,204 to HK$40,738, a HK$29,534 spread on the same certified stone. Taylor and Hart lists it at HK$40,738. 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.
