Listed at 14 retailers as of November 2, 2026, with prices from $405 to $2,480, a $2,075 spread on the same certified stone. Do Amore Diamonds lists it at $2,480. 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.
