Listed at 16 retailers as of October 29, 2026, with prices from HK$5,336 to HK$47,549, a HK$42,214 spread on the same certified stone. Brilliant Earth lists it at HK$47,549. 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.
