2. Metals to Consider Earrings can be comprised of a variety of precious and non-precious metals including gold, silver, and nickel-based alloys. When choosing earrings, it is important to note that certain metals have been known to cause allergic reactions in some people. This is especially true of nickel-based metals, small amounts of which are found in stainless steel. If metal allergies are a problem for you, then you’ll probably want to look for hypo-allergenic earrings made of either titanium or niobium. 3. Matching Earrings to You Color is another important consideration in earring selection. A nicely colored earring should complement your eyes and facial complexion as well as your outfit. Experiment with an assortment of colors until you find ones that draw out your complexion and go well with the colors that dominate your wardrobe. Remember: You buy earrings to match your outfit, not outfits to match your earrings!
