Listed at 17 retailers as of October 31, 2026, with prices from $604 to $6,307, a $5,703 spread on the same certified stone. Brilliant Earth lists it at $6,307. 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.
