Listed at 7 retailers as of October 26, 2026, with prices from $161 to $1,010, a $848 spread on the same certified stone. MOH London lists it at $1,010. 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.
