Listed at 11 retailers as of November 4, 2026, with prices from $726 to $1,585, a $859 spread on the same certified stone. Flawless Fine Jewelry lists it at $1,585. 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.
