Listed at 16 retailers as of October 29, 2026, with prices from $912 to $3,678, a $2,766 spread on the same certified stone. Taylor and Hart lists it at $3,678. 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.
