Listed at 3 retailers as of October 29, 2026, with prices from $698 to $1,169, a $471 spread on the same certified stone. The Diamond Guys lists it at $1,169. 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.
