Listed at 6 retailers as of November 1, 2026, with prices from $457 to $1,499, a $1,042 spread on the same certified stone. MOH London lists it at $1,499. 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.
