It is possible to treat natural clear quartz (and occasionally other suitable minerals, such as danburite) in a process that bonds atoms of precious metals to the exterior / matrix of the crystal. These enhanced crystals have a coloured appearance, depending on the metals used in the process, and carry an added energy that, unlike "dyed" crystals, add to and extend the usual attributes of the base material. These crystals, as well as a few man-made minerals such as Gaia stone and Pink Lazurine, are very usable in crystal healing and meditation etc. their uses vary widely according to their nature
AQUA AURA: is treated with gold, resulting in the crystals having a rich aquamarine colour with subtle rainbow flashes. This was one of the first treated minerals to be created, and is probably the most useful for healing purposes. This is a gentle but profound crystal, very useful when used to strengthen, clear and balance the communication centres (throat and brow) and to enhance and support communication of all sorts, whether this be verbal, written or telepathic. This is also a great stone for encouraging Angelic connections. The gold aspect also makes this an excellent crystal for working with any problems where the nervous system, cellular structure or DNA is in need of repair or adjustment.
