Listed at 8 retailers as of November 3, 2026, with prices from HK$2,126 to HK$14,789, a HK$12,663 spread on the same certified stone. Blue Nile lists it at HK$14,789. 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.
