Listed at 13 retailers as of October 30, 2026, with prices from HK$4,725 to HK$31,932, a HK$27,207 spread on the same certified stone. Brilliant Earth lists it at HK$31,932. 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.
