Listed at 19 retailers as of November 3, 2026, with prices from $484 to $3,514, a $3,030 spread on the same certified stone. Helzberg Diamonds lists it at $3,514. 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.
