Carnelian rough materials

Carnelian is a form of Quartz known as Chalcedony. It is a crypto-crystaline form of Quartz.

Carnelian is a good hard material with a hardness of 7. It is brittle so you need to be somewhat careful when setting it.

Carnelian ranges from nearly opaque to very translucent.

The color of Carnelian can vary from a dark brown (also known as Sardonyx) to a reddish brown and aldo a very orangy red.

Below you will see examples of some of the material we have in stock.
