Recycled aluminum is very hypo-allergenic and also is very tarnish resistant ... meaning it does not turn black like sterling silver, brass or copper does so there is a lot less maintenance.
Recycled Sterling Silver – Naturally, all sterling silver jewelry will tarnish over time. This is not indicative of poor quality. If you notice your jewelry discoloring or losing its luster, use a polishing cloth to help bring back the shine.
General Care – Avoid contact with lotions, perfumes, and beauty products. Remove jewelry before washing hands and showering. Avoid harsh chemicals and cleaning agents. I do not recommend swimming in swimming pool as chlorine in the water can cause damage. I recommend storing jewelry in a jewelry box will help to prevent tarnishing when you are not wearing it.
