A mother's ring is a type of memorial jewelry. It has a birthstone for each of the children of a woman, either living or dead. They can represent a mother or grandmother's family, can include birthstones for other family members, and can be given upon the birth of a new child or grandchild.
The name is trademarked since 1959 by jewelry company John C. Nordt Co.
Standard birthstone rings feature the birthstone of the ring's wearer, but mother's rings include the birthstones of all of her children. In some cases the birthstones of the parents are also set in the ring. Some are also personalized with the names of family members, or the family name.
Similar rings, often featuring the birthstones of both her children and grandchildren, are sometimes given to grandmothers as well. These rings are popular Mother's Day gifts, and are often given to a mother or grandmother upon the birth of a new child or grandchild, both as a new ring or to replace an old one.
