Listed at 14 retailers as of November 1, 2026, with prices from $461 to $2,292, a $1,831 spread on the same certified stone. MOH London lists it at $2,292. 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.
