Listed at 9 retailers as of November 2, 2026, with prices from $489 to $1,633, a $1,144 spread on the same certified stone. MOH London lists it at $1,633. 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.
