You have probably seen half-dollar sized light catchers around. Most likely you just assumed these prismatic globes where decorative ornaments. While they are pretty to look at faceted spheres, also known as feng shui crystals actually serve a greater purpose than just looking pretty.

 Refraction

While these crystals obviously refract light casting beautiful bright rainbows all around them, that is not the only reason for their placement. Along with light, these crystals refract energy. While some crystals are designed to absorb or amplify the energy around them, these crystals serve to balance an energy pull. Picture a wind tunnel wind blows right through it at a rapid rate, and can often be damaging. Putting an obstacle in its way can slow the wind creating a calm breeze. These crystals work in the same way. If you have a downward pull of energy in your home you can simply hang one of these crystals in the path to catch and refract the energy out in different directions. This is especially helpful in stair ways and hallways.

Containment

To best understand this picture a rushing river, with a partial dam at the end where it meets a lake. If you have large picture windows or numerous windows chances are a lot of the positive energy entering your home is quickly slipping right back out these windows. Hanging a Faceted sphere will not only add a sparkling light display it will contain and diffuse the energy flow redirecting it back into your home. 

Bonus Brightness

These crystals can also be used to brighten the energy and light in your workspace. They can help refract back the negative energies from those around you will reflecting back the energy you have created in your space. The light and colors they produce can also help energize and brighten the space you are working in. Considering most people spend upwards of 8 hours a day inside in manufactured lighting this can be a significant energy boost.
