Listed at 17 retailers as of October 29, 2026, with prices from $156 to $1,500, a $1,344 spread on the same certified stone. Do Amore Diamonds lists it at $1,500. 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.
