Listed at 9 retailers as of November 3, 2026, with prices from $831 to $2,231, a $1,400 spread on the same certified stone. MOH London lists it at $2,231. 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.
