Listed at 21 retailers as of November 2, 2026, with prices from $746 to $4,430, a $3,684 spread on the same certified stone. Brilliant Earth lists it at $4,430. 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.
