Listed at 17 retailers as of October 28, 2026, with prices from $436 to $3,045, a $2,609 spread on the same certified stone. Brilliant Earth lists it at $3,045. 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.
