Listed at 14 retailers as of October 31, 2026, with prices from HK$1,820 to HK$10,435, a HK$8,615 spread on the same certified stone. Brilliant Earth lists it at HK$10,435. 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.
