Listed at 11 retailers as of November 6, 2026, with prices from $635 to $5,822, a $5,187 spread on the same certified stone. Brilliant Earth lists it at $5,822. 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.
