Agate is a cryptocrystalline variety of silica, chiefly chalcedony, characterised by its fineness of grain and brightness of color. Although agates may be found in various kinds of rock, they are classically associated with volcanic rocks and can be common in certain metamorphic rocks.
The stone Agate was given its name by Theophrastus, a Greek philosopher and naturalist, who discovered the stone along the shore line of the river Achates in present-day Sicily, sometime between the 4th and 3rd centuries BC. Most agates occur as nodules in volcanic rocks or ancient lavas, in former cavities produced by volatiles in the original 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, giving a banded appearance to the section. Such stones are known as banded agate, riband agate and striped agate.
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.
Cubuk Agate found only in Cubuk, a district in Central Anatolia-Ankara, Turkey. Good multi-colored stick and pseudomorph agates are very rare. The stones show different band widths with different colors. Tones of red, brown, yellow, green and gray are the colors you can see. Stick-like minerals and color bands sometimes produce beautiful motifs from which the stone gets its name, like “Landscape Agate,” “Picture Agate,” “Eye Agate,” “Stick Agate,” or “Tube Agate.”
