Listed at 3 retailers as of October 28, 2026, with prices from $686 to $1,149, a $463 spread on the same certified stone. The Diamond Guys lists it at $1,149. 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.
