Ah, a 923 stamp on jewelry means that the piece is made of a special type of silver called "Sterling Silver." It's a high-quality metal that is often used in jewelry making because it's durable and beautiful. So, when you see that stamp, you can feel confident that your jewelry is made with care and will last a long time.
