Crafts that can be worn are considered jewelry, these include amulets, crowns, bracelets, earrings and rings. Jewelry can provide protection from damage, but does so rarely, as the coverage is minimal. Wearing jewelry does not interfere with wearing other items. Dwarves who wear high-quality jewelry may get happy thoughts from "putting on an exceptional/masterwork item" or from "making a satisfying acquisition".
Types of Jewelry
♀ Amulets are worn on the head, presumably this models things worn around the neck in the real world like necklaces. The equipment limit is not known.
µ Crowns are worn on the head as a cover layer item. Unlike other jewelry, a crown provides 20 coverage, so has a chance to deflect attacks directed at the head (as evidenced here). Unfortunately, crowns also conflict with helms. Dwarves can somehow wear multiple crowns at once, with the highest reported count being at five crowns.
Ö Bracelets are worn on the hands. The equipment limit is not known.
δ Eleven earrings can fit on each ear. Earrings will be put first on the right ear, then on the left ear, alternating until both are full.
ö Rings can be worn on the fingers and toes. Rings will be put first on the thumb, right hand; then on thumb, left hand; then on first finger, right hand; then on first finger, left hand; and so on. Once all the fingers have a ring, rings will be put on the toes starting with the first toe, right foot; then first toe, left foot; etc.; looping until each digit has eleven rings for a total of 220 rings.
Sometimes, during world generation, when one historical figure kills another historical figure, that figure will be wearing a piece of jewelry made from the figure it killed when you encounter it in adventurer mode or fortress mode. For example, the goblin general leading invaders to attack your fortress might be wearing a +dwarf tooth ring+ from the hapless dwarven soldier he struck down fifty years ago. Or, while adventuring in adventure mode, you may meet an elf wearing a -human hair crown- from the peasant they killed and ate over a century ago during a war over the eating of sapient creatures. The trophy behavior is controlled by an ethics tag in the entity raws. You may have migrants or guests with equipped trophies.
Jewelry does not interfere with adventurers wearing armor or clothing. Crowns and amulets are worn on the head over helms. Earrings are worn on alternating ears. Bracelets are worn on alternating hands over gloves and under gauntlets. Rings are worn on alternating digits, starting with thumbs, then fingers, and lastly toes. There is a soft limit of 99 items per location, such that once all locations for an item type have 99 items on them, any more worn will always go on the first location. For example, if a creature has 99 earrings on each ear, wearing more will put them only on the right ear. There is effectively no limit for items with only one location, like crowns (the weight of them does add up, though).
