Vessonite

Vessonite also known as Idocrase or Vessuvianite after its discovery on Mount Vesuvius in 1795 can also be found in Switzerland and Canada. 

It is typically found in a green or chartreuse color, but may also be formed in yellow to brown, yellow-green, red, black, blue or purple hues. 

According to the Mohs scale, Vesuvianite measures 6.5, which is quite impressive and good for jewelry. 

This stone is believed to be very energetic, as it aligns with the heart that helps the person in bringing comprehensiveness and reliability.
