Listed at 16 retailers as of October 29, 2026, with prices from $436 to $3,870, a $3,434 spread on the same certified stone. Do Amore Diamonds lists it at $3,870. 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.
