Agate Slice - Dyed Purple Agate (RefPCS9)

Agate is a cryptocrystalline variety of silica, chiefly chalcedony, characterised by its fineness of grain and brightness of colour. Although agates may be found in various kinds of rock, they are classically associated with volcanic rocks and can be common in certain metamorphic rocks.

   

This piece of Agate has been dyed Purple.
