Listed at 16 retailers as of November 2, 2026, with prices from $431 to $1,984, a $1,554 spread on the same certified stone. Reve Diamonds lists it at $1,984. 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.
