Listed at 5 retailers as of October 30, 2026, with prices from $237 to $1,852, a $1,615 spread on the same certified stone. Blue Nile lists it at $1,852. 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.
