Listed at 16 retailers as of November 6, 2026, with prices from $16,071 to $25,985, a $9,914 spread on the same certified stone. MOH London lists it at $25,985. 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.
