These two stones are confused for one another, and some people even think they are the same stone. It’s important to know that these two stones are not the same. The features and looks of marble & onyx stones differ considerably. We will explain the differences between these two stones so that you do not mix them up.
One type of metamorphic rock that is produced when limestone undergoes metamorphosis is onyx. Onyx belongs to the group of metamorphic rocks, which are sedimentary rocks like limestone that have undergone “metamorphosis” because of heat and deep burial. However, marble is a member of the sedimentary rock group, which also includes limestone, the main difference between these two types of rocks I how they are generally formed.
In other words, onyx is a better form of marble that undergoes natural processing.
The colors of onyx vary between white, gray, black, green, purple, yellow, and red. However, pure white onyx has a transparent color. Also, calcite, the most stable type of calcium carbonate, is the main component of onyx. Unlike marble, onyx has a backlit feature because of the massive, distinct crystals in this mineral. So you can see the light passing through when you put your phone`s flashlight behind the onyx stone. This feature of onyx stone is also utilized by architects and designers, who put LED panels behind this exquisite stone to add a spectacular touch of natural beauty to the place.
Because of this, the cost of this stone is higher than marble stone, and it is also more beautiful and transparent with a polished surface.
Marble is less expensive and less resistant than an onyx stone since it is regarded as a lower-quality variety of onyx stone. It`s important to know that marble stones can have quite lovely colors and patterns that onyx stones might not have. For instance, Golden black marble and spider marble stones have distinctive patterns.
Stone artifacts such as sculptures and flower pots are the main uses for onyx stones, then wall and floor stones, building facades, and tombstones, which are often utilized in slab form. Due to its expensive cost, this stone will be found more often in luxurious and sophisticated buildings like Hotels, restaurants, halls, and complex lobbies. Also, onyx stone is used for wall cladding and flooring of religious buildings.
Marble is almost as equally used as onyx, with the exception that its primary use is in buildings, then its secondary use is in stone artifacts.
Polishing: Depending on the usage, marble is used in two forms: polished and unpolished. While onyx stone is always used with a polished surface.
Cuts And Dimensions: Onyx is frequently cut into tile or slabs. However, marble is cut into slabs and tiles with large and small sizes.
In comparison to marble, onyx stone is more expensive. Depending on the type of onyx and marble being compared, its cost can be estimated to be approximately ten times that of marble.
