Listed at 8 retailers as of October 27, 2026, with prices from $327 to $3,025, a $2,698 spread on the same certified stone. Brilliant Earth lists it at $3,025. 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.
