This is a unique way to show Mom that she truly is an angel! An angel mother's ring is a ring that has an angel for the design surrounded by the birthstones of her children on it. What is very special about a ring like this is that upon first glance, you may not notice the angel, as it is very discreetly and beautifully mixed in with the birthstones. Some believe that angel mother's ring will provide the mother wearing it with protection from the angels above. If an angel mother's ring interests you, try doing an Internet search for the topic.
You could also purchase a mother's ring pendant. A mother's ring pendant is actually smaller versions of a mother's ring with a separate child birthstone for each ring. The rings are designed to hang from a chain around your neck. This is a neat an unique way to wear mothers' rings.
