Listed at 13 retailers as of November 1, 2026, with prices from $551 to $2,385, a $1,834 spread on the same certified stone. MOH London lists it at $2,385. 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.
