Listed at 14 retailers as of October 29, 2026, with prices from $112 to $1,023, a $911 spread on the same certified stone. MOH London lists it at $1,023. 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.
