Listed at 19 retailers as of October 30, 2026, with prices from $167 to $923, a $756 spread on the same certified stone. MOH London lists it at $923. 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.
