Listed at 2 retailers as of October 30, 2026, with prices from $2,291 to $5,711, a $3,420 spread on the same certified stone. Taylor and Hart lists it at $5,711. 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.
