BLACK NETWORK AGATE
The popular Black Network Agate is a chalcedony, otherwise known as microcrystalline quartz.
Agate minerals have the tendency to form as nodules on or within the cavities of pre-existing volcanic rocks. These cavities are formed when gases are trapped within the liquid volcanic material forming vesicles. According to Wikipedia, cavities are then filled in with silica-rich fluids from the volcanic material, layers are deposited on the walls of the cavity slowly working their way inwards. The first layer deposited on the cavity walls is commonly known as the priming layer. Variations in the character of the solution or in the conditions of deposition may cause a corresponding variation in the successive layers. These variations in layers result in bands of chalcedony, often alternating with layers of crystalline quartz forming banded agate. Hollow agates can also form due to the deposition of liquid-rich silica not penetrating deep enough to fill the cavity completely. Agate will form crystals within the reduced cavity, the apex of each crystal may point towards the center of the cavity.
The priming layer is often dark green but can be modified by iron oxide resulting in a rust-like appearance. Agate is very durable and therefore is often seen detached from its eroding matrix, once removed, the outer surface is usually pitted and rough from filling the cavity of its former matrix. Agates have also been found in sedimentary rocks, normally in limestone or dolomite; these sedimentary rocks acquire cavities often from decomposed branches or other buried organic material. If silica-rich fluids are able to penetrate into these cavities agates can be formed.
Agate forms by the deposition of silica from groundwater in the cavities of igneous rocks. The color lies in the various embedded materials. Each bead is unique and may not be perfectly symmetrical. Black Network is known for its beautiful white striations.
Agate was originally discovered in the Achates River in Sicily somewhere between 400-300 BC. However, varieties of agate can be found all over the world.
Agate’s chemical formula is Si02 or Silicon dioxide. It has a hardness rating of 6.5 – 7, making it a great gem for jewelry.
Then mount four rows of precious stones on it. The first row shall be carnelian, chrysolite and beryl; 18the second row shall be turquoise, lapis lazuli and emerald; 19the third row shall be jacinth, agate and amethyst; 20the fourth row shall be topaz, onyx and jasper.
