Distinctive blue coloured chalcedony mineral exhibiting a dull and slightly waxy lustre. Chalcedony is a microcrystalline variety of quartz which means its crystals are so small they can only be seen with the aid of strong magnification.
In its purest form chalcedony is white but inclusions of other minerals cause stones to occur in a wide variety of different colours. Although the blue variety tends to be known simply as chalcedony, most other colours have their own unique name. When it occurs with distinctive bands it's known as agate, with an apple green colour it's chrysoprase and the reddish orange variety of chalcedony is better known as carnelian.
Chalcedony is relatively hard and grades 7 on Mohs scale of mineral hardness. It's a porous stone hence much of the subtle coloured material ends up being dyed in an attempt to make it more appealing to the wider commercial market.
In crystal healing chalcedony is used to balance the energy of the mind, body, emotions and spirit and is said to alleviate hostility and an irritable mood. It's also said to enhance generosity and help increase mental stability.
