Cleansing crystals regularly is necessary as they will absorb negative energy. It is likely that your crystals may absorb vibrations not only from you ... but from anything in the environment where they are located. To create positive energy within your crystals... you need to cleanse them frequently.

This is important as their effectiveness for healing may be effected by negative vibrations within the stones. If you have been using them to heal health issues or when you were in a negative frame of mind... they would probably have absorbed your negative energy. This is why it is a good idea to purify them on a regular basis.
If you have been thinking about why you should cleanse your crystals, and you use them regularly... understand that your crystals are tools. You need these tools to be at the highest vibration possible, so that you may receive the most benefit from using them. Many people go to great lengths to clean their home, their clothes and themselves... yet neglect to remove the negativity from the crystals they are using.
A crystal singing bowl may be used to cleanse your crystals. There are two ways to do this. If the stones are small you may put them into the crystal singing bowl.
For bigger items... place them close to the bowl... then play the bowl for a few minutes. The lovely crystal bowl music is very powerful and the sounds emitted by the bowl will resonate throughout the room.
As the strong vibration of the pure crystalline sound of your crystal singing bowl fills the crystals... it will drive out any negative energy. This will lift the vibration of any of your crystals that are close by. The room will also be filled with good vibrations as well.
There are different methods for cleansing natural crystals of various types. Using white light is a powerful method once you know how to create it. Most of you have the capacity to create white light.
The first time you do it... close your eyes and ask the universe to create white light. This is similar to the power of prayer. Imagine your body filling with the light... then feel the added energy that you have within you.
Open your eyes and direct the white light. Use your hands in a small sweeping motion towards where you want to direct the white light. Ask the universe to use the white light to transmute any negative energy within the stone into positive energy.
The white light can also be used on yourself to bring your vibration up... or use it to improve the energy of the room. I like to cleanse my personal stones fairly often... and this is important if you are doing a daily crystal meditation using them. White light is the easiest and most effective method to remove any built up negative energy quickly.
Cleansing crystals by smudging them is easy. So how do you smudge crystals?
The most potent smudge to use is white sage.
It is possible to buy smudge sticks ready made in a smudging stick... or you can use loose sage leaf.
It is easy to buy in most places, and the smudge sticks are made up of either white sage alone or mixed with lavender. Some may have other fragrant herbs in them as well.
Sage smoke is powerful to cleanse both your stones and the environment where they live.
Hold the stones within the stream of the smoke... or simply hold your smudge stick near to where they are sitting so the air around them is full of the sage essence. This is the method most alchemical healers use, to quickly cleanse their stones and crystal wands after use on clients.
The moonlight has a powerful influence that will re-energize your crystals... and allow them to lift their vibrations naturally. A good time to for cleansing crystals is at the time of the full moon... when it is at its brightest.
Place them somewhere in your home where they will be in the moonlight for as long as possible. Leave them there overnight if you are able to. By absorbing the energy of moonlight... you will allow their vibration to naturally lift.
Cleaning Quartz crystals is easier than other types of natural crystals as they like water. To clean quartz crystals any or all of the above methods may additionally be used. You can clean quartz crystal using running water.... or in a container of water.
If you are doing Quartz Crystal Healing... ensure that your crystals are cleansed regularly... to ensure the vibrations within the stones are most effective. As quartz is highly programmable... while cleansing it you might tell it to release and let go of any negativity within it. By programming it to release negativity... it will aid other crystals nearby to stay cleaner and may not need cleaning as frequently.
Cleansing crystals is necessary, even if you may not feel that your crystals have any reason to be cleaned. It is a good practice to regularly put your crystals out in the moonlight... around the time of the full moon when it is at its brightest.
Regular smudging will revitalize them and lift their vibration. Cleaning crystals regularly ensures they will be at their best to assist you as you use them in your life.
