Onyx is a striking and versatile stone known for its distinctive black color. However, onyx can also display a range of other hues, including white, brown, and red, often arranged in parallel bands. This unique banding is a result of its formation process, where layers of minerals accumulate over time.
What Colors Can Onyx Be?
While black onyx is the most recognized, onyx is available in various colors. These colors are typically formed by the presence of different minerals during its formation. Here are some common colors and their characteristics:
- Black Onyx: The most popular and widely used type, known for its deep, solid black appearance.
- White Onyx: Features a translucent white color, often with subtle veining.
- Brown Onyx: Exhibits warm, earthy tones, ranging from light tan to deep chocolate.
- Red Onyx: Displays rich red hues, often with bands of white or brown.
How Is Onyx Formed?
Onyx is a type of chalcedony, a cryptocrystalline form of silica, composed of fine intergrowths of quartz and moganite. It is formed in the gas cavities of lava, where silica-rich water seeps into the cavities, depositing layers of minerals over time. This process results in the unique banding patterns that onyx is known for.
Uses of Onyx in Jewelry and Design
Onyx is highly valued in the world of jewelry and interior design due to its aesthetic appeal and versatility. Here are some common uses:
- Jewelry: Onyx is often used in rings, necklaces, and bracelets, either as a solid stone or combined with other gemstones to create striking contrast.
