Armlets are a type of jewelry that are worn around the upper arm, just above the elbow. They can be made from a range of materials, including precious metals, gems, glass, and other decorative elements. Some common types of armlets include:

1. Simple bands: thin, delicate bands that are worn around the arm, often made from precious metals such as gold or silver.
2. Bangle armlets: armlets made from multiple interlocking bangles, often featuring decorative elements such as gems, beads, or other embellishments.
3. Cuff armlets: wide, rigid armlets that hug the upper arm, often featuring an opening at the front or back.
4. Charm armlets: armlets featuring small, decorative charms or pendants, often worn to symbolize important events or milestones.
5. Link armlets: armlets made from a series of interlocking links, often made from precious metals such as gold or silver.
6. Beaded armlets: armlets made from a series of beads strung together on a cord or string.

Armlets can be worn for both fashion and functional reasons, and can be paired with a range of outfits to create a desired look. They can be simple and understated, or elaborate and ornate, and can be made from a wide range of materials to suit a range of tastes and styles. In many cultures, armlets have symbolic meaning, and are often given as gifts to commemorate special occasions or to express affection.
