Listed at 2 retailers as of November 2, 2026, with prices from $714 to $1,002, a $289 spread on the same certified stone. Diamond Quarter lists it at $1,002. 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.
