Listed at 23 retailers as of October 30, 2026, with prices from $885 to $4,968, a $4,083 spread on the same certified stone. Brilliant Earth lists it at $4,968. 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.
