Listed at 9 retailers as of October 29, 2026, with prices from $1,270 to $7,631, a $6,361 spread on the same certified stone. MOH London lists it at $7,631. 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.
