Listed at 5 retailers as of October 29, 2026, with prices from $310 to $1,185, a $875 spread on the same certified stone. MOH London lists it at $1,185. 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.
