Listed at 15 retailers as of October 30, 2026, with prices from $914 to $5,588, a $4,674 spread on the same certified stone. Do Amore Diamonds lists it at $5,588. 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.
