Listed at 15 retailers as of October 27, 2026, with prices from HK$1,514 to HK$10,750, a HK$9,235 spread on the same certified stone. Brilliant Earth lists it at HK$10,750. 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.
