Listed at 16 retailers as of October 30, 2026, with prices from $1,426 to $12,670, a $11,244 spread on the same certified stone. Do Amore Diamonds lists it at $12,670. 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.
