Listed at 4 retailers as of October 30, 2026, with prices from $419 to $1,600, a $1,181 spread on the same certified stone. Do Amore Diamonds lists it at $1,600. 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.
