Listed at 14 retailers as of November 4, 2026, with prices from $265 to $2,276, a $2,011 spread on the same certified stone. Do Amore Diamonds lists it at $2,276. 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.
