Listed at 10 retailers as of November 5, 2026, with prices from $782 to $4,587, a $3,805 spread on the same certified stone. MOH London lists it at $4,587. 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.
