Listed at 8 retailers as of October 31, 2026, with prices from $368 to $1,667, a $1,299 spread on the same certified stone. Taylor and Hart lists it at $1,667. 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.
