Listed at 4 retailers as of October 28, 2026, with prices from HK$8,678 to HK$12,083, a HK$3,405 spread on the same certified stone. Zales lists it at HK$12,083. 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.
