Agate polished to show its internal patterns, translucency and colours.  

Agate is a term for irregularly- and concentrically-layered masses of microcrystalline quartz. Layers consist of translucent or opaque, microcrystalline, fibrous quartz called chalcedony. Impurities in different layers create different colours such as clearish-whitish-grayish, brownish-red, and yellowish-brown.

Agates can be metamorphic or volcanic in orgin.
