Listed at 12 retailers as of October 29, 2026, with prices from $23,639 to $46,474, a $22,835 spread on the same certified stone. MOH London lists it at $46,474. 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.
