Listed at 16 retailers as of October 30, 2026, with prices from $4,161 to $18,299, a $14,138 spread on the same certified stone. Taylor and Hart lists it at $18,299. 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.
