Uses of Fire Opal

Fire Opal is an attractive form of translucent opal that has less commercial value than precious opal. This stone is mainly used for jewelry and is cut into cabochons, faceted gems, and other shapes, depending on the quality of the specimen. The stone is not very hard and is therefore used in low-wear jewelry, like pendants and earrings.

Healing Properties of Fire Opal

Fire Opal is said to increase wealth. It's supposedly particularly beneficial for those suffering from low self-esteem. Wearing fire Opal is suggested to encourage loyalty in your life and providing excitement in intimate relationships. This stone may enable you to let go of negative memories and thoughts you've been holding on to.
