Listed at 6 retailers as of October 27, 2026, with prices from $324 to $658, a $334 spread on the same certified stone. Taylor and Hart lists it at $658. 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.
