More about Agate

Agate is chalcedony quartz that forms in concentric layers in a wide variety of colors and textures. Each individual agate forms by filling a cavity in host rock. As a result, agate is often found as a round nodule, with concentric bands like the rings of a tree trunk. The bands sometimes look like eyes, fanciful scallops, or even a landscape with trees.

Agate was used as a gemstone by the Egyptians at least 3,000 years ago. In modern times, agate has a special association with the Idar-Oberstein region in Germany. Idar-Oberstein was an important source of agate until the 19th century, and the region was favored with good local sandstone for producing cutting and polishing wheels, and water power to work the wheels.

Fortunately for Idar-Oberstein, large deposits of agate were discovered in Brazil in the 1830's, just as the agate mines in Germany were starting to be worked out. The agate polishing industry in Germany flourished as a result and produced high quality object d'arts, beads, rings, pendants, brooches and cameos.

Today agate continues to be mined in Brazil, but also in Uruguay, India, Australia, China, Madagascar, Mexico, Mongolia, Namibia and New Mexico.
