Listed at 12 retailers as of October 28, 2026, with prices from $542 to $1,719, a $1,177 spread on the same certified stone. Rare Carat lists it at $1,719. 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.
