Listed at 22 retailers as of October 30, 2026, with prices from $378 to $3,474, a $3,096 spread on the same certified stone. Brilliant Earth lists it at $3,474. 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.
