Listed at 16 retailers as of October 27, 2026, with prices from $982 to $6,935, a $5,953 spread on the same certified stone. Brilliant Earth lists it at $6,935. 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.
