Listed at 14 retailers as of November 6, 2026, with prices from $317 to $2,443, a $2,126 spread on the same certified stone. Do Amore Diamonds lists it at $2,443. 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.
