Listed at 11 retailers as of November 5, 2026, with prices from $1,679 to $6,298, a $4,620 spread on the same certified stone. MOH London lists it at $6,298. 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.
