Listed at 22 retailers as of October 30, 2026, with prices from $365 to $1,938, a $1,573 spread on the same certified stone. Reve Diamonds lists it at $1,938. 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.
