Listed at 24 retailers as of November 2, 2026, with prices from $445 to $4,169, a $3,724 spread on the same certified stone. Brilliant Earth lists it at $4,169. 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.
