Listed at 6 retailers as of October 29, 2026, with prices from $339 to $1,549, a $1,211 spread on the same certified stone. Taylor and Hart lists it at $1,549. 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.
