Listed at 6 retailers as of November 1, 2026, with prices from $715 to $1,746, a $1,031 spread on the same certified stone. MOH London lists it at $1,746. 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.
