Listed at 19 retailers as of October 31, 2026, with prices from $592 to $3,759, a $3,167 spread on the same certified stone. Brilliant Earth lists it at $3,759. 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.
