Listed at 9 retailers as of November 5, 2026, with prices from $4,068 to $12,769, a $8,701 spread on the same certified stone. MOH London lists it at $12,769. 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.
