Listed at 5 retailers as of October 29, 2026, with prices from $282 to $2,067, a $1,785 spread on the same certified stone. Blue Nile lists it at $2,067. 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.
