What is the ruling on wearing a silver ring with a stone alongside another "wedding" ring on the same finger and hand, and what is the legal weight of a silver ring?

A woman is permitted to wear more than one ring on her hand or on a single finger, whether it be gold or silver. As for a man, he is not permitted to wear gold, but he is allowed to wear silver, regardless of the number of rings. There is no specific weight prescribed by Islamic law for a ring.
