Listed at 5 retailers as of October 28, 2026, with prices from $547 to $2,378, a $1,831 spread on the same certified stone. MOH London lists it at $2,378. 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.
