These four charms are all a bit different.  3 are of caged birds, and I've painted one pink, one blue, and one blue with a blushed pink tummy. (1" tall)

The fourth charm is of two birds on a branch. They are blue with pink tummies.

No two will be exactly the same, since each is hand painted. All will be the colors described, though.

All of the charms were well primed, painted with acrylic paint, antiqued with a brown glaze, then top coated with clear poly for durability.  I'd say they are fine to use in jewelry, and should withstand normal wear.  I wouldn't go swimming while wearing the charms, or give them a heavy duty scrubbing, but for average, every day use, they are good.
