Listed at 2 retailers as of October 29, 2026, with prices from $852 to $1,076, a $224 spread on the same certified stone. Brilliant Earth lists it at $1,076. 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.
