Listed at 7 retailers as of October 28, 2026, with prices from $459 to $1,596, a $1,137 spread on the same certified stone. MOH London lists it at $1,596. 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.
