Listed at 23 retailers as of November 2, 2026, with prices from $432 to $4,159, a $3,727 spread on the same certified stone. Do Amore Diamonds lists it at $4,159. 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.
