Listed at 24 retailers as of October 23, 2026, with prices from $1,066 to $6,880, a $5,814 spread on the same certified stone. Brilliant Earth lists it at $6,880. 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.
