Listed at 17 retailers as of October 26, 2026, with prices from $419 to $3,320, a $2,901 spread on the same certified stone. Do Amore Diamonds lists it at $3,320. 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.
