Listed at 4 retailers as of November 4, 2026, with prices from $2,248 to $4,446, a $2,198 spread on the same certified stone. MOH London lists it at $4,446. 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.
