Listed at 25 retailers as of October 30, 2026, with prices from $453 to $3,912, a $3,459 spread on the same certified stone. Brilliant Earth lists it at $3,912. 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.
