Listed at 7 retailers as of November 6, 2026, with prices from $368 to $2,206, a $1,838 spread on the same certified stone. Brilliant Earth lists it at $2,206. 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.
