Listed at 22 retailers as of October 30, 2026, with prices from $3,538 to $23,013, a $19,475 spread on the same certified stone. Brilliant Earth lists it at $23,013. 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.
