Listed at 13 retailers as of October 28, 2026, with prices from $602 to $5,690, a $5,088 spread on the same certified stone. Brilliant Earth lists it at $5,690. 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.
