Listed at 5 retailers as of November 5, 2026, with prices from $339 to $1,504, a $1,165 spread on the same certified stone. MOH London lists it at $1,504. 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.
