Listed at 4 retailers as of November 2, 2026, with prices from $414 to $1,181, a $767 spread on the same certified stone. MOH London lists it at $1,181. 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.
