Listed at 16 retailers as of October 30, 2026, with prices from $223 to $2,140, a $1,918 spread on the same certified stone. Do Amore Diamonds lists it at $2,140. 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.
