Listed at 18 retailers as of November 1, 2026, with prices from $444 to $1,969, a $1,525 spread on the same certified stone. MOH London lists it at $1,969. 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.
