Listed at 24 retailers as of October 30, 2026, with prices from $382 to $2,787, a $2,405 spread on the same certified stone. Brilliant Earth lists it at $2,787. 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.
