Listed at 19 retailers as of October 27, 2026, with prices from HK$3,162 to HK$16,740, a HK$13,578 spread on the same certified stone. Queensmith lists it at HK$16,740. 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.
