After agonizing about what to wear to the speed-dating event you have talked yourself into attending, you come to the realization that the perfect accessory to wear for the evening is one of your favorite chains. You only have a few minutes to make and form an impression, and wearing an eye-catching chain should help in both respects. If he does not like your jewelry, you have no reason to like him, and that is that. Chain necklaces are available in many different metals, but gold is the most popular choice. Gold chains come in the classic yellow gold metal, as well as in white and rose gold. Other types of metals you can choose from are silver, bronze, and platinum. Many chains are plain, without embellishments. Designers create these chains to hold pendants, which you can also purchase separately. Diamond chains are more formal than plain ones, and contain one or more small or large diamond embellishments along the chain. Of course, other gemstones can be worn on chains as well. On eBay, you can find a huge inventory of chains and pendants for both men and women. Decide what kind of impression you want to make, and make it in your own confident style.
