You can go here for mothers ring if you want to give a gift to your mother for certain occasions like birthdays, mother’s days, anniversaries, etc.
I did not know that there are traditional mother’s rings which are supposedly alike in size and shape with a birthstone in the center, made of gold or sterling silver. Recently though, variations came like side stones in the middle of the center stone, stackable rings that represent each child, and engraves.
I would personally choose a stackable mother’s ring. The two stacks will be a symbol of love for my children, of course, each with their birthstone on each ring.
