Listed at 12 retailers as of October 28, 2026, with prices from $257 to $1,831, a $1,574 spread on the same certified stone. Helzberg Diamonds lists it at $1,831. 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.
