Listed at 12 retailers as of November 5, 2026, with prices from $163 to $1,683, a $1,520 spread on the same certified stone. MOH London lists it at $1,683. 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.
