The birthstone for August is peridot, which is often associated with strength and protection. The lime green colour of a Peridot Rosary can be a reminder to pray for the spiritual growth and livelihood of loved ones. 

 

Here are some other things to know about peridot: 

 

The Romans called peridot the "evening emerald" because it doesn't change color in artificial light. 

 

Peridot is a mineral in the Alvine group, and its chemical composition includes magnesium, iron, silicon, and oxygen. 

 

Most peridot crystallizes from melted rock material deep inside the earth, and is then brought to the surface by volcanic eruptions. 

 

The St. Carlos Indian Reservation in Arizona is a leading producer of peridot, but it is also mined in China.
