Listed at 18 retailers as of November 1, 2026, with prices from $342 to $2,935, a $2,592 spread on the same certified stone. Do Amore Diamonds lists it at $2,935. 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.
