Listed at 10 retailers as of November 5, 2026, with prices from $3,295 to $10,885, a $7,590 spread on the same certified stone. MOH London lists it at $10,885. 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.
