Listed at 16 retailers as of October 29, 2026, with prices from $690 to $4,270, a $3,580 spread on the same certified stone. Brilliant Earth lists it at $4,270. 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.
