Listed at 7 retailers as of November 5, 2026, with prices from HK$721 to HK$2,978, a HK$2,257 spread on the same certified stone. Brilliant Earth lists it at HK$2,978. 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.
