Listed at 12 retailers as of October 30, 2026, with prices from $2,786 to $13,857, a $11,072 spread on the same certified stone. Do Amore Diamonds lists it at $13,857. 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.
