Yes. Jewelry stores have mezuzot you can wear as pendants.
Jewelry that is uncomfortable or jewelry that you make have an allergic reaction to should not be worn.
There are two parts of the Mezuzah, The Mezuzah Scroll itself and the Mezuzah Case. The Mezuzah Scroll is made with ink on parchment of a Kosher animal. The case can be made of almost any material as its purpose is to protect the scroll. Most common materials for the mezuzah case are metal, stone, wood and glass.

There is no limit to the size of a Mezuzah. Attached is a video of the largest known mezuzah recently installed at Ben Gurion Airport.
An ornament worn on the feet is a nupur. It is a piece of jewelry worn around the ankles (an ankle bracelet).
The scroll inside the mezuzah is written in Hebrew.
The origin of the mezuzah is from the "Shema" in which is mentioned the core beliefs of Judaism and its teachings. Therefore, the "purpose" of the mezuzah is as a reminder, when entering and leaving the home, of the mezuzah's message. The mezuzah contains a parchment inscribed with a passage from the Torah (from Deuteronomy ch.6 and ch.11), placed on Jewish doorposts.
Incase you get ring-sting.
