Collection: Agate – Meaning, Properties & Origin | Gemstone Encyclopedia

Agate is a semi-precious stone known for its characteristic color layers, which are clearly visible within the stone. Despite its opacity, it often appears slightly translucent, lending a special radiance to any piece of jewelry. As early as the third millennium BC, the Sumerians crafted agate into jewelry and utilitarian objects. The stone owes its name to the Achates River in Sicily.
Mineralogy

Agate is a microcrystalline variety of quartz (silicon dioxide) that forms in igneous rocks. Gases trapped in volcanic rock created cavities, where aqueous solutions containing quartz were deposited. Over long periods, minerals settled in multiple layers – these differing deposits create the characteristic color layers of agate.

Agate cannot be cleaved; its fracture is uneven. With a hardness of 7 on the Mohs scale and a density of approximately 2.7 g/cm³, it is robust and durable. After discovery, the agate nodule is sawed open and polished, revealing its colors and glassy luster.
Color Varieties of Agate

Agate is available in many colors: brown, red, orange, green, white, and yellow are typical. The individual color layers are often separated by white lines. Colors such as pink, purple, magenta, or cobalt blue do not occur naturally; such stones are industrially dyed.
