Listed at 10 retailers as of October 28, 2026, with prices from HK$3,633 to HK$12,790, a HK$9,157 spread on the same certified stone. Brilliant Earth lists it at HK$12,790. 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.
