What is the difference between onyx and marble?
Onyx and marble are both natural stones with distinct characteristics. Here are some key differences between the two:
1. Formation: Onyx is a type of chalcedony, which is formed in the caves from mineral-rich water. Marble, on the other hand, is a metamorphic rock that forms when limestone is subjected to intense heat and pressure.
2. Color and Appearance: Onyx typically has a translucent appearance with bands of color running through it. It often comes in shades of white, brown, yellow, and green, but other colors like red and blue are also found. Marble, on the other hand, is typically opaque and ranges in color from pure white to various shades of gray, beige, pink, and green.
3. Veining: Marble is renowned for its veining patterns, created when minerals like graphite, iron, or clay mix with the limestone during formation. This veining gives marble a unique and elegant look. Onyx also has banding, but it is typically more regular and defined, resembling parallel stripes or bands.
4. Translucency: One of the most distinguishing features of onyx is its translucency, allowing light to pass through it. This property makes onyx popular for decorative applications such as backlit panels, countertops, and lamps. Marble, however, is not translucent.
5. Hardness: Marble is a relatively soft stone, ranking around 3-4 on the Mohs scale of hardness. It can be prone to scratching and etching. On the other hand, onyx is harder than marble, ranking around 6-7 on the Mohs scale.
6. Applications: Marble is commonly used for various applications like countertops, flooring, wall cladding, and sculptures due to its elegant appearance. Onyx, with its translucent property, is often used for decorative purposes like countertops, bar tops, vanities, and light fixtures.
It is important to note that both onyx and marble require regular maintenance and care to preserve their beauty and longevity.
