Agate
Agate is a multicoloured variety of chalcedony, characterised by its fine band structures and layered patterns. The colours result from different minerals deposited in layers during formation. Agate has been used for jewellery and decoration for thousands of years because of its attractive appearance and wide variety of shapes.
Major deposits include Brazil, Uruguay, India, the United States and Madagascar. Agate forms in volcanic rocks and is often found in geodes. Its chemical formula is SiOâ‚‚, as it is a form of quartz. Agate has a hardness of 6.5 to 7 on the Mohs scale.
Known variants: Botswana Agate, Crazy Lace Agate, Moss Agate and Flower Agate are some popular and in demand types, each with its own distinctive pattern and colouring.
