Agate is a cryptocrystalline variety of silica, chiefly chalcedony, characterised by its fineness of grain and brightness of color.

The stone 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. Colorful agates and other chalcedonies obtained over 3,000 years ago from the Achates River, now called Dirillo.

A very small sample of some of the many agates which found all over the world. A hard stone agates found in all colors of the rainbow, although green and blue are quite rare.
