Listed at 15 retailers as of October 28, 2026, with prices from $13,005 to $22,800, a $9,795 spread on the same certified stone. MOH London lists it at $22,800. 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.
