Listed at 17 retailers as of October 27, 2026, with prices from $533 to $4,229, a $3,696 spread on the same certified stone. Queensmith lists it at $4,229. 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.
