Listed at 11 retailers as of November 1, 2026, with prices from $750 to $4,139, a $3,389 spread on the same certified stone. Brilliant Earth lists it at $4,139. 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.
