Violine

Violine gems were purple and volcanic in nature.

Description
Found in deposits mixed with other minerals and occasionally of exceptional (up to human fist) size, this ornamental stone was usually cut cabochon and polished, or faceted baguette style. A typical stone had a base value of 10 gp.

Powers
This gem was proof against mummy rot. A creature with mummy rot only had to touch a violine crystal and the mummy rot was removed. The violine was completely consumed by this process. If this stone came into contact with an actual mummy, it burst and damaged the mummy. If a mummy was destroyed by contact with violine, the resulting mummy dust was inert and could not be used as a spell component or for other magical purposes.
