Brass is a natural material, it will oxidize and form a patina or tarnish when it exposed to air or moisture. The outlook of the brass might be varied and might have visible scratches & spots due to the production process. It will not affect the clarity or impression of the seal. You can use sandpaper to bring its luster back or clean it in an eco-friendly way, such as lemon juice.
