Listed at 10 retailers as of November 1, 2026, with prices from $208 to $1,073, a $865 spread on the same certified stone. MOH London lists it at $1,073. 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.
