Listed at 17 retailers as of October 30, 2026, with prices from $306 to $1,683, a $1,378 spread on the same certified stone. Reve Diamonds lists it at $1,683. 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.
