Listed at 12 retailers as of November 4, 2026, with prices from $5,502 to $9,999, a $4,497 spread on the same certified stone. MOH London lists it at $9,999. 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.
