This is a detail of a slice of blue lace agate.
I love the abstract feel.It reminds me of the amoebas I used to draw in biology lab.
Most agates occur as nodules in volcanic rocks or ancient lavas where they represent cavities originally produced by the disengagement of volatiles in the molten mass which were then filled, wholly or partially, by siliceous matter deposited in regular layers upon the walls. Agate has also been known to fill veins or cracks in volcanic or altered rock underlain by granitic intrusive masses. Such agates, when cut transversely, exhibit a succession of parallel lines, often of extreme tenuity, giving a banded appearance to the section. Such stones are known as banded agate, riband agate and striped agate.
The first deposit on the wall of a cavity, forming the "skin" of the agate, is generally a dark greenish mineral substance, like celadonite, delessite or "green earth", which are rich in iron probably derived from the decomposition of the augite in the enclosing volcanic rock. This green silicate may give rise by alteration to a brown iron oxide (limonite), producing a rusty appearance on the outside of the agate-nodule. The outer surface of an agate, freed from its matrix, is often pitted and rough, apparently in consequence of the removal of the original coating. The first layer spread over the wall of the cavity has been called the "priming", and upon this base zeolitic minerals may be deposited.
Many agates are hollow, since deposition has not proceeded far enough to fill the cavity, and in such cases the last deposit commonly consists of drusy quartz, sometimes amethystine, having the apices of the crystals directed towards the free space so as to form a crystal-lined cavity or geode.
On the disintegration of the matrix in which the agates are embedded, they are set free. The agates are extremely resistant to weathering and remain as nodules in the soil or are deposited as gravel in streams and shorelines.
Certain stones, when examined in thin sections by transmitted light, show a diffraction spectrum due to the extreme delicacy of the successive bands, whence they are termed rainbow agates. Often agate coexists with layers or masses of opal, jasper or crystalline quartz due to ambient variations during the formation process."

Blue lace agate,which is also called blue lace chalcedony and the gem of ecology,comes from Nanibia,South Africa.It was given its name by George Swanson who found it on his farm in Nanibia.He choose the name because the blue and white lacy swirls reminded him of the clouds as seen from space.The stone is opaque to translucent.
Blue lace agate is associated with the element of air,the throat and crown chakras (for energy work and crystal healing practices)and the astrological sign of Pisces. Blue lace agate is said to have a calming effect on people - bringing a sense of tranquility and helping one to reach higher spiritual planes.Inspiration,as well as the fostering of intuition and inner knowledge are other attributes of the blue lace agate.Because of it's association with the throat chakra, blue lace agate is considered a stone of communication.It is supposed to ease communication during difficult times and situations ,and enhances public speaking in general.
In crystal healing practices,blue lace agate is used to help reduce or cure stuttering, to aid with arthritis,headaches to name a few.
All agates are considered to be protective stones.The qualities of this variety are more gentle than some others.
