Personally:
Beauty: the doe, the swan, the moon, flowers of any sort, espcially roses (for strength- organge, beatuty- white or pink), pearls, rose quarts, dresses.
Strength: sigil of a hammer, the sun, any large tree, hemetite stones, tiger's eye stones, lion, buck, horns, sword, spears.
The list goes on, and they are sterotypcial to be sure, but there are some examples.
