Listed at 9 retailers as of October 29, 2026, with prices from $348 to $973, a $625 spread on the same certified stone. MOH London lists it at $973. 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.
