Listed at 20 retailers as of October 27, 2026, with prices from $479 to $4,255, a $3,776 spread on the same certified stone. Do Amore Diamonds lists it at $4,255. 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.
