Tiger's eye
Tiger's eye is a yellow-brown vitreous mix of limonite, quartz and riebeckite. It is also called chatoyant. According to Breanna Redwin, the tiger's eye symbolizes the grounding earth energy combined with the light energy of the sun. Thus it can be used to help those who are unfocused and can also help dreamers distinguish wishes from needs.
The tiger itself has powerful symbolism. Think, for example of the song "Eye of the Tiger" by Survivor. This stone evokes feline power in a concentrated form by evoking this golden eye.
