Listed at 7 retailers as of November 1, 2026, with prices from $478 to $1,651, a $1,173 spread on the same certified stone. MOH London lists it at $1,651. 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.
