Listed at 4 retailers as of October 30, 2026, with prices from $432 to $1,160, a $728 spread on the same certified stone. Brilliant Earth lists it at $1,160. 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.
