means Decorative objects worn on the body — rings, necklaces, bracelets, and the like — typically made of precious metals and gemstones.

from From the Old French 'jouel' or 'joel,' meaning a trinket or gem, which gave English 'jewel.' The trail likely runs back to Latin 'jocus,' meaning a joke or plaything — so a 'jewel' may share roots with the idea of something delightful and amusing, a sparkling toy for grown-ups. The British spell it 'jewellery'; Americans trimmed it to 'jewelry,' but both still wear the same Latin twinkle.
