Listed at 9 retailers as of October 26, 2026, with prices from $998 to $5,970, a $4,972 spread on the same certified stone. Brilliant Earth lists it at $5,970. 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.
