Listed at 16 retailers as of November 2, 2026, with prices from $773 to $6,484, a $5,711 spread on the same certified stone. Brilliant Earth lists it at $6,484. 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.
