Listed at 17 retailers as of October 30, 2026, with prices from $303 to $1,522, a $1,219 spread on the same certified stone. Reve Diamonds lists it at $1,522. 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.
