Listed at 15 retailers as of November 4, 2026, with prices from $347 to $3,487, a $3,140 spread on the same certified stone. Do Amore Diamonds lists it at $3,487. 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.
