Crystal clusters have strong vibrational energies because they have many points combined together.  They are especially powerful with their output of energy. The points in a cluster vibrate together harmoniously to bring positive energy and transmute negativity in any space they are in. They are perfect for any room in the home or office and are great for meditation. I like to have them in every room depending on their healing properties.

Towers and points energy is directed upward and out. Wherever they are placed they emit a very focused and directional energy that affects the area around it as well as any other crystals that are nearby. They are good for the center of a grid, in the corners of a room for feug shui to create an energy vortex, and to hold for calm and focus whether at home or the office.

Spheres emit their energy from all sides and have very balancing vibrational energy which provides harmony, stability, and unity.

Tumbled Stones are perfect to carry and for meditation because of their size. They are great to fidget with to stay focused. I keep mine in my bedroom and choose different ones each day depending on what I am attracted to.
