Listed at 8 retailers as of October 30, 2026, with prices from $1,360 to $6,025, a $4,665 spread on the same certified stone. Helzberg Diamonds lists it at $6,025. 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.
