Listed at 18 retailers as of October 30, 2026, with prices from $1,320 to $11,728, a $10,408 spread on the same certified stone. Do Amore Diamonds lists it at $11,728. 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.
