A mother’s ring or pendant is usually given by a child of the mother, which is a relatively new idea. And the idea is to put all of the children's birthstones (sometimes also with children's name engraved) in a ring, that's a mother's ring for mom.

There are no rules when it comes to a mother's ring. A lot of times, you'll just see them as a plain ring with different stones for the different children, or they can be more decorative with different stones.
