Description

agate

Agates from Agate Creek North Queensland (400kms from the Atherton Tablelands) are known amongst collectors as the most colourful agates in the world with spectacular patterns. They are usually found in volcanic rocks, in seams filling fractures or in cavities left by gas bubbles and occur in limitless combinations of colour and pattern, making each specimen unigue. Agate is a banded chalcedony which is a type of fine-grained quartz with a dense structure of interlocking, fibrous crystals and some hydrous silica. In its purer form, chalcedony is a translucent, white, grey or bluish material with a waxy lustre.
