Listed at 9 retailers as of November 4, 2026, with prices from $498 to $1,477, a $978 spread on the same certified stone. MOH London lists it at $1,477. 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.
