During a recessionary economy people still value the addition of a nice jewelry accessory to their wardrobe. Having a wide variety of accessories in the marketplace ensures that a range of budgets can afford these "everyday" pieces of jewelry. Everyday accessories can be defined as stylish and fun, less expensive jewelry. It can be made from silver or metal as long as it is still a quality piece. It would not be worth the money it if it is just a cheap looking piece of jewelry that will deteriorate or not last for a while. If it's dispensable, then a lot of money should not be spent on it.
When it comes to affordable accessories, sometimes buying in sets makes the most sense. Then you can have a matching set of earrings, necklace, and bracelet that makes your accessorizing an easy task. You can also mix and match pieces to create your own individual look.
Most fine jewelry stores will have more affordable items in their inventory in addition to the fancier, costly items. Just because they carry such a line, does not dilute the fact that they still sell quality. In fact, those stores that specialize in higher end jewelry probably have better quality and selection of the lower prices items.
Even some high fashion jewelry designers are switching out to more affordable products and raw materials such as wood and vine. What this absolutely says is that in a down turned economy, jewelry is not considered just a luxury item anymore; it is one that we adapt to make sure we can still include in our wardrobes.
