Listed at 11 retailers as of November 6, 2026, with prices from $897 to $3,824, a $2,928 spread on the same certified stone. Brilliant Earth lists it at $3,824. 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.
