Listed at 29 retailers as of November 2, 2026, with prices from $305 to $3,420, a $3,115 spread on the same certified stone. Brilliant Earth lists it at $3,420. 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.
