Listed at 14 retailers as of October 28, 2026, with prices from $317 to $1,506, a $1,189 spread on the same certified stone. Helzberg Diamonds lists it at $1,506. 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.
