I always get my husband and I a Fu bracelet every Lunar New Year regardless of our Chinese zodiac signs. It is generally for good luck, safety, and health.
Traditionally it is a red corded bracelet with a 24k piece.
For durability of the bracelet itself I often get him a beaded bracelet with a 24k pixiu or 24k ruyi.
We are switching to 18k this year because eventually the gold gets damaged and falls off and we don't want the dogs accidentally finding a piece and eating it.
For myself, I usually get a corded bracelet for comfort. I already wear a lot of metal on my wrists, so I prefer a corded bracelet. Sometimes I'll choose gold, sometimes I won't have any gold at all. More of a personal preference for me. But for me, there's always some red in it.
Usually if it is your zodiac year, you just need to have something red on you at all times. A very easy way to do this is red underwear or red Fu bracelet (preferably blessed at a temple).
