The History and Meaning of Agate
Agate is an ancient mineral first mentioned in the 3rd century BC. It is believed that the Greek philosopher Theophrastus, who was the first to describe the stone, named it after the Achates River in Sicily. According to another version, the name of the mineral comes from the Greek ‘agates’ meaning happy.
Agate crafts and jewelry were found in Egyptian tombs as well as ancient burials in England and the Urals. Our ancestors believed that the stone could ward off storms. It was placed under pillows to allow sleepers to see vivid dreams. The stone incorporated into a ring gave prudence, and agate inlays in earrings could protect from negative thoughts. The ancient Romans associated it with the goddess of fertility Ceres. Every Roman farmer and gardener had agate stones. They placed them in their gardens to protect the crop from bad weather.
Chemical-Physical Properties of Agate
Agate is a volcanic gem that occurs as a result of the accretion of various minerals of the silica family (SiO2), with chalcedony being a dominant mineral. Most commonly, it has a layered structure in the form of bands or concentric stripes. These layers come in different colors and can have varying degrees of translucency. Thanks to this, cross-section cuts reveal original, never-repeating patterns.
The hardness of agate is 6.5-7.0 on the Mohs scale. After polishing, its surface acquires a glassy luster, although the fracture is more matte and waxy. Agate can be partially translucent or completely opaque.
The variety of colors and fancy ornaments appear due to the gradual layering of chalcedony as well mineralization of voids. Such minerals as rock crystal or hematite fill hollows and cracks in mother rock. Agate’s decorative properties and ease of cutting make it highly valued among jewelers.

Fire agate features a banded rainbow effect combined with shimmering, as if burning, particles of hematite.
Fortification agate got its name because of the multitude of concentric layers, which resemble defensive structures from a bird's eye view.
Iris agate is perhaps the most striking type thanks to multiple bands of all possible colors. However, the stone reveals its patterns only when bright natural light hits its surface.
Star agate is a rare variety that displays a 4-, 6- or 12-beamed star when being cut en cabochon.
Landscape agate is a very beautiful type of agate displaying pictures of nature made up by the duets of contrasting colors. Landscape agates have their own varieties such as ruins and clouds.
