Description and Characteristics
Bull's Eye (also known as Red Tiger's Eye) is essentially Tiger's Eye that has undergone thermal processes, either naturally (through geothermal heat) or artificially. This heating oxidizes the iron present in the crocidolite fibers, transforming the original golden color into a brownish-red or deep garnet. It retains the spectacular chatoyancy (cat-eye effect), where a band of bright light appears to move across the surface of the stone when tilted. As a variety of microcrystalline quartz, it is a hard and durable stone, ideal for all types of jewelry and amulets.

Did you know...?
It is very common for the Bull's Eye found in shops to have been artificially heated in kilns to achieve that vibrant red color; however, its physical properties and beauty remain intact. In ancient times, it was believed that this stone granted the wearer the strength and bravery of an ox, making it a common amulet among warriors. To maintain its silky luster, it only needs simple cleaning with warm water and mild soap, avoiding chemicals that could dull its surface.
New-Age Properties
Bull's Eye is considered the stone of "vital force" and physical stamina. Unlike Tiger's Eye, which focuses on the mind, Bull's Eye acts directly on the body and the root chakra. It is used to provide courage, motivation, and extra energy during times of exhaustion. Spiritually, it is a stone of great protection that helps set clear boundaries and defend oneself against unfair criticism. It is excellent for overcoming apathy and for grounding spiritual energies into the physical plane, allowing ideas to turn into concrete actions.
