Onyx Stone Slab or Onyx Marble is a metamorphic rock composed of limestone metamorphism and its main mineral is the most stable form of calcium carbonate. This mineral has large and distinct crystals, and Its most prominent feature is the passage of light through it due to its high purity and transparency (unlike marble).
For this reason, the price of this stone is higher than other stones and they also have a very high beauty, shine, and transparency.
The name “onyx” is derived from the Greek “ὄνυξ” meaning “claw” or “nail, so called because the mineral’s color sometimes resembles that of a human fingernail, pink with white streaks.
In ancient Egypt, marble was very popular among the people because of its transparency. For example, it was used to make small perfume and healing oils bottles (called Alabastra), and also sacred Greek sculptures.
Onyx Marble is one of the best and most expensive buildings and decorative stones in the world, which is available in various natural colors and designs in Iranian mines. This stone is generally used in the walls and interior of the building. This stone can also be used in floors and interior walls. In Iran, the Onyx slab has been used in the tombs of famous Imams.
Also, placing Onyx slabs in symmetry with each other in the form of a book match and four-match will make this natural product much more beautiful. It can be used in the walls of houses, lobbies, hotels, halls, restaurants, as well as shopping malls.

Keep in mind that marble has more pores than granite, so more care and maintenance is needed, because these stones are calcium-based, which means they have a softer surface and react with acidic detergents. Also onyx is a porous natural stone therefore it will quickly absorb liquids. Onyx stones should be sealed twice a year.
So to clean onyx stones, you should look for products with a neutral pH level. Be careful not to use detergent directly on the onyx marble.
