Listed at 4 retailers as of October 28, 2026, with prices from $621 to $1,452, a $831 spread on the same certified stone. MOH London lists it at $1,452. 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.
