Listed at 13 retailers as of October 29, 2026, with prices from $750 to $4,291, a $3,541 spread on the same certified stone. MOH London lists it at $4,291. 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.
