Listed at 21 retailers as of October 30, 2026, with prices from $607 to $5,394, a $4,787 spread on the same certified stone. Do Amore Diamonds lists it at $5,394. 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.
