Listed at 19 retailers as of November 3, 2026, with prices from HK$1,295 to HK$8,078, a HK$6,784 spread on the same certified stone. Reve Diamonds lists it at HK$8,078. 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.
