Listed at 16 retailers as of November 4, 2026, with prices from $322 to $2,017, a $1,695 spread on the same certified stone. Reve Diamonds lists it at $2,017. 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.
