Listed at 21 retailers as of October 28, 2026, with prices from $4,561 to $19,545, a $14,983 spread on the same certified stone. Taylor and Hart lists it at $19,545. 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.
