Listed at 18 retailers as of October 29, 2026, with prices from $569 to $2,475, a $1,906 spread on the same certified stone. MOH London lists it at $2,475. 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.
