Listed at 23 retailers as of October 26, 2026, with prices from $383 to $1,857, a $1,474 spread on the same certified stone. MOH London lists it at $1,857. 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.
