Listed at 5 retailers as of November 6, 2026, with prices from $317 to $1,500, a $1,183 spread on the same certified stone. Taylor and Hart lists it at $1,500. 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.
