Listed at 14 retailers as of November 2, 2026, with prices from $185 to $1,133, a $948 spread on the same certified stone. MOH London lists it at $1,133. 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.
