The right piece depends on how tough the stone is. These suggestions follow GIA's hardness and toughness notes for each stone.

Stone	Best as	Why
Diamond	Any piece, including an everyday ring	Hard and tough enough for a ring worn every day, as well as pendants, earrings and bracelets.

For a mom: a pendant or bracelet with each child's birthstone. Mix tougher stones with delicate ones only in pendants.
For a partner: stud earrings or a simple pendant in her own stone are easy to wear with anything.
