Listed at 31 retailers as of October 29, 2026, with prices from $3,141 to $23,890, a $20,749 spread on the same certified stone. Do Amore Diamonds lists it at $23,890. 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.
