Listed at 18 retailers as of November 4, 2026, with prices from $426 to $2,405, a $1,979 spread on the same certified stone. Reve Diamonds lists it at $2,405. 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.
