Listed at 10 retailers as of October 28, 2026, with prices from $448 to $1,190, a $742 spread on the same certified stone. Brilliant Earth lists it at $1,190. 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.
