Composition: Black onyx is primarily composed of silicon dioxide (SiO2), the same chemical compound that makes up quartz. The black coloration is typically due to the presence of organic material or iron oxide.
Appearance: It has a smooth texture and a uniform black color. Sometimes, it may have white or lighter-colored bands or streaks, known as agate.
Formation: Onyx forms in the cavities of lava rock, where silica-rich water flows. Over time, the water evaporates, leaving behind layers of quartz. Black onyx specifically may form when black carbon-rich solutions seep into the rock, staining the quartz.
Uses: Black onyx has been used for millennia in jewelry and ornamental objects. It is often cut into cabochons, beads, or used in rings, necklaces, and other forms of jewelry. Its sleek black appearance makes it a popular choice for both men's and women's jewelry.
Metaphysical Properties: In metaphysical beliefs, black onyx is associated with strength, protection, and grounding. It is believed to absorb and transform negative energy, making it a popular stone for spiritual and healing practices.
