I realize aluminum doesn't sound like the sexiest of metals, but I truly believe it is underrated. The "bright" is what makes it different from a soda pop can in that it won't blacken skin - and it's shinier, as in, "bright".
Aluminum is lightweight making it my favorite go-to for earrings, it doesn't tarnish, cleaning is simple, and it also helps to keep the costs down on some of the more complicated pieces I make. I love it.
Content: ~ 93-95% aluminum, ~ 1% magnesium
Allergy: Allergic reactions are rare
To clean: Mild soap and water. That's it. Know that bright aluminum will slowly corrode over time losing its high sheen but that it only will effect its surface layer.
