Listed at 9 retailers as of November 1, 2026, with prices from $1,800 to $5,964, a $4,164 spread on the same certified stone. MOH London lists it at $5,964. 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.
